    Naim Audio Mu-so Review

    1-Pixel.png

    Imagine this: You place an audio playback system in your living room and enjoy the hell out of your favorite music with your family and friends. This is something I could only imagine, but for many people this is something they remember. Back in the day people placed a stereo console in their living rooms and partook in all the fun that goes along with listening to music with others. Sadly, over the years these “beautiful” pieces of audio furniture were replaced by separate components and soon relegated to man caves. The wonderful hobby of listening to music moved from a shared experience to a companionless commitment. Even worse than a room in the basement, where there’s a chance the guys could hang out for a while and listen to a couple tracks before being summoned upstairs to join the rest of the party, is the solitary loneliness of listening to music through headphones. The shared experience of listening to music has been obliterated by keep-it-to-yourself audio and the antisocial pseudo-communal experience of sharing yourself with others online, but only from the comfort of your empty house. I am way over on the introvert side on the introvert / extrovert continuum, but I still enjoy sharing the things I love with friends and family … while the friends and family are physically in the room, not simply reachable via Internet Protocol from an iPad in an isolated nook of my living room. In addition to sharing the music I love with others, the ability to share high quality sound with others is also important. Without an easily accessible and conveniently placed high end audio system in a common living space, this sharing of good sound just isn’t going to happen. Sure, my three year old daughter comes down to my listening room now and then, but imagine if I could bring all the music and all the quality to her on a daily basis. That would be priceless. While the dream of doing this is priceless, the reality of doing this here and it’s made possible my England’s Naim Audio. Having the Naim Mu-so in my house has enabled me to bring my favorite (and my daughter’s favorite) music, in high quality, to her and has enabled me to share the fine qualities of a high end component with friends who had no idea such a product exists. I don’t know how many times I’ve told friends that a Bose iPod dock isn’t the height of living, but now I can casually let them experience the joys of high quality music and fine craftsmanship while getting together to create new shared experiences we’ll remember for a lifetime.[PRBREAK][/PRBREAK]

    The Mu-so

     

    In the last several years there have been all kinds of somewhat similar products that while cool, just didn’t do it for me. Or, maybe I was simply blind to what was in front of me and it took me longer than most to realize what a critical role this category of product can play in the lives of high quality music aficionados. Either way, the Naim Audio Mu-so is here and it’s high quality in both sight and sound.

     

    The technical specifics of the Mu-so are very good, but are much less interesting to me than its end game, producing music for people’s enjoyment. Briefly, the Mu-so has six custom drivers setup as a pair of three way loudspeakers. Each physical drive unit is powered by its own 75 watt digital amplifier. The entire system is controlled by a 32 bit digital signal processor, making this active loudspeaker system completely optimized for high end playback. One of my favorite technical features that intersects with aesthetics is the Naim engineered internal antenna. I don’t know how many products I’ve had in my system that feature the ultimate in ugliness, the old faithful of WiFi devices since the late 1990s, the rubbery plastic wireless antenna. The Mu-so does not “feature” this antithesis of high quality. The Mu-so’s built-in antenna not only can’t be seen, but it works terrific. The wireless worked so well during this review period that it blew well past Naim’s stated specs for high resolution file support. According to Naim, the Mu-so only supports sample rates up through 48 kHz when sent to the unit via 802.11 b/g (2.4 GHz) WiFi. Yes, you read that correctly, the Mu-so only features 802.11 b/g wireless, not 802.11n or 802.11ac. I guess good engineers can eek out every ounce of performance from even an old WiFi standard. When streaming music to the Mu-so I monitored WiFi traffic to and from the unit. My monitor showed the Mu-so maxing-out the 802.11g WiFi capabilities at 54 Mbps, but playback remained problem-free. Back to streaming higher resolutions than the stated Naim maximum of 48 kHz. The maximum sample rate supported by the Mu-so is 24/192, so I figured I would cut right to the chase and stream 24/192 via WiFi. To my surprise 24/192 files played back without a hiccup. These high resolution files even played gapless! That’s better than some high end components can do wired, let alone wireless. Is my situation an anomaly? I’m unsure. A search of Google did indicate some users experiencing week WiFi issues with he Mu-so, but I’m sure a Google search of any wireless product would reveal the same. When it comes to WiFi, there’s no substitute for trying the product in one’s own environment. Those lucky enough to have wired Ethernet near a Mu-so can simply plug the unit in and never worry about any WiFi issues.

     

    The Mu-so supports a surprising number of input methods and services including UPnP, AirPlay, Bluetooth (aptX), USB (for USB drives or portable players), Tidal, Spotify Connect, Internet radio, optical (TosLink), and even good ole analog. Bringing all of this together is Naim’s very well designed iOS / Android application. Selection of the input or source service is done with a simply tap of the finger on a specific icon. The app is one of the only apps that I’d recommend people stick with, even if they are using UPnP. I usually tell people to just use JRiver with JRemote if they want to stream UPnP. However, the Naim app is very good and worthy of people’s time to get used to it. Sure there are some things that JRemote can do that the Naim app can’t, such as edit metadata embedded in the file or display tag values for dynamic range, but for the most part most people will probably be very happy with Naim’s app. Well done Naim. My one complaint about the app is its inability to preset some podcast channels for easy access. To listen to The Adam Carolla Show I had to browse into Podcasts by Genre > Comedy > the search for Adam Carolla to find KFIR’s ACS channel. It would be so much better if I could set KFIR as a preset like I can with other Internet radio channels within the Naim app, but this in’t the case right now. It would also be nice if Naim could embed full Spotify browsing and playback within the app for Spotify Connect, but Spotify has allowed almost nobody to do this. Selecting the Spotify icon within the Nam app simply brings up a page that says, launch the Spotify app. once something is playing, the Naim app can control it a bit through forward and back and volume buttons, but it’s too limited for practical use with tens of millions of tracks available. Fortunately, this wont’ be an issue for most audiophiles because they likely don’t stream Spotify’s lossy offerings anyway.

     

     

    Using the Mu-so

     

    I briefly touched on some of the technical aspects above, but what really thrills me about the device is my experience listening to the Mu-so. To me, the Mu-so is all about good aesthetic design, good sound quality, and good Tidal integration within the Naim iOS app. There was no way I was getting a component into our living room unless it visually appealed to everyone in the house. By everyone, I mean my wife. To us, the Mu-so passed the looks test and it’s pleasant to view every day. The switchable front grills are nice as is the ability to raise and lower the intensity of the lighting underneath the unit.

     

    Sound reproduction through the Mu-so is better than 99% of the devices in this category. I didn’t say 100% because I haven’t heard them all, but I can make an educated guess based on what I’ve heard and what I know is available. One can’t expect the Mu-so to replace a full HiFi system, but they also can’t expect a full HiFi system to replace the Mu-so in a civilian living room. What one can expect is for the Mu-so to easily outperform products like the ubiquitous Sonos and likely all the other devices sitting next to the Mu-so in the Apple Store. Many dealers I’ve talk to over the years have always said they wish they had something to offer customers that worked like a Sonos but offered something more high end in all categories namely sound quality. The Naim Mu-so is definitely the product to replace Sonos in homes where people care about sound quality. During the review period I sent everything in the direction of the Mu-so, from Metallica to Menudo (wait, what? Did I just write that) to Leonard Cohen to Iggy Azalea to Prince to Nicki Minaj to Peter, Paul and Mary, because that’s how I listen to music when using a device like the Mu-so. I don’t sit in my kitchen listening for the back hall ambiance of a Keith Johnson Reference Recording while I prepare something for my daughter to eat. Rather, walk around the house or sit in a room listening to whatever moves me at the moment or whatever is going to get my daughter to dance and recite lyrics. Since she was two year old my daughter has been really in to the band Journey. For example, today she came to me and asked me to play Journey and wanted to skip the first track, going right into her hat trick of favorites, Don’t Stop Believin’, Wheel In The Sky, and Faithfully. And yes, she sings the words, dances, and plays the air drums during Faithfully. This is what it’s all about. Exposing my daughter to great music and high quality sound and to watch her be a toddler dancing like nobody is watching. What’s more, I can do this every day of the week because I’ve brought the experience to her rather than wait for her to come down to my listening room. The Mu-so enables me to accomplish all of this while checking off the required boxes of aesthetics, sound quality and great app with Tidal integration.

     

    Note: The settings within the app allow the user to dis/enable the Loudness function. I preferred listening with Loudness disabled as I thought it added a bit too much bass.

     

    Speaking of the app and Tidal integration, the Mu-so to me is all about accessibility. Accessibility in that it’s easy to use the app and stream tens of millions of lossless quality tracks with the tap of a finger and it integrates with how I live, playing music at home and while mobile with Tidal in both scenarios. How so? Naim’s Tidal integration enables the user to create or add to a Tidal playlist within the Naim app, and have that Tidal playlist appear wherever one uses Tidal. On my iPhone and within Roon the Tidal playlists are the same as they are in the Naim app. It’s great when technology follows what the user wants rather than when technology makes the user act a certain way that is the opposite of anyone except a software developer. The Naim Tidal integration is a bit like Roon in that it displays some of the information surrounding an artist or specific release. For example browsing the Artist St. Paul and the Broken Bones, one can tap on a paragraph of text that explains a bit about the band. Within the text one can tap artists names such as James Brown and be taken directly to the James Brown Tidal page. Browsing this band’s album named Half the City enables the user to view information about the album such as a write-up and guitarist, bassist, producer, and mastering engineer. None of the aforementioned metadata is hyperlinked like it is in Roon, but Roon is the exception to the rule when it comes to music discovery in this manner. As expected by now, the Naim Tidal integration displays all of one’s favorite artists, albums and tracks, in addition to all the Tidal selections for What’s New, Tidal Rising, and Tidal Discovery. Granted the Tidal-selected music in these areas has changed since new management took over, but nonetheless this is still available for one’s perusal within the Naim app, as is the age old method of simply searching for what one wants (it’s very fast by the way).

     

     

    Wrap Up

     

    The reason all of us entered into this hobby was because of the music and how it made is feel emotionally. We didn’t start purchasing sterile HiFi gear only to find out we could play something called music through said gear. Music brings out emotion like few other things in this world. What can make the emotional experience even better for many of us is getting closer to the performers and the actual sound of the recordings through great HiFi components. In addition, the ability to share both our favorite recordings and high quality reproduction with our friends and family is hard to put a price on. The Naim Mu-so enables us to overcome many barriers to bringing music back into our every day lives. The Mu-so’s high end build quality, aesthetic appearance, comparatively small size, high sound quality, and well made remote application make it the perfect piece to place almost anywhere in one’s home or office. When tens of millions of tracks are available in high quality at our fingertips we are guaranteed to enjoy this wonderful hobby even more and share what we’ve known forever with our loved ones. Great music is one thing, but add in the element of high quality playback and the listeners can be transported to places only limited by the imagination. The Mu-so has enabled me to share more music and high quality sound with my daughter, in a short period of time, than any piece of HiFi gear I’ve used in her three years on this planet. That fact alone makes the Mu-so worth its weight in gold. As soon as my daughter asks for Pearl Jam in high resolution, the Mu-so will literally be priceless.

    No dislike of Naim here, I have auditioned a few pieces of their equipment and although I didn't end up buying I don't have a negative opinion of them. But by judging some of the comment here the reviewer, and by possibly by extension Naim, has not done an adequate job of explaining the product. Take my comments out of the equation, when there are comments that basically say 'I don't get it' you have a marketing and information problem! If we can't call the product a dud maybe we have to call the review a dud then!

     

    The problem is that any product in a relatively new category is going to be a bit tricky to define. Naim call the Mu-so a Wireless Music System. I think that sums it up perfectly, but I can easily imagine other persons having no idea what a wireless music system is. As for marketing, despite any confusion about what it is, it is selling well.

    You're right... It's interesting (with specific reference to the MuSo) how people's opinions on the Naim forum changed... Most (of those posting) dismissed it when Naim first launched it, only for many to slowly change over time. And these are die hard "audiophiles".

     

    Products like this, the Devialet and Naim NAC-N 272 are where audio is heading, reducing boxes and increasing "convinience" while at the same time keeping a high quality sound.

     

    Yep. Plus these products have the potential to appeal to consumers who are not stereotypical audiophiles. Consumers who value both convenience and aesthetics, but still want good sound quality.

    That is the essence of why one should deal with all of the complications these toys. I see listening to music becomes more and more not a shared experience (especially reproduced music) but a singular thing and thus the rise of headphones, music played in isolation. That is definitely a cultural shift!

    After being thoroughly entertained with her plain spoken (while at the same time being in perfect Queen's English !!) analysis (head firmly planted in arse at times with respect to "what" defines true "audiophile " quality sound & this device represents the future of audio...) I believe she is absolutely correct on BOTH points...

    BAD NEWS FOR NAIM BUT GOOD NEWS FOR ALL AUDIOPHILES....

    I was at the apple store attempting to listen to the Naim Mu-so without any luck as it was very noisy. But the salesman came over and provided great news. He said if you are interested in Naim i would recommend to wait for 2 days more....we have a great new audio system coming...

    DEVIALET!!!!

    I was very excited...hopefully now the mass population will get some exposure to great audio...

    I personally have not heard it but salesman said he has...and for additional $500 you get far superior audio system than the Naim.

    The Devialet hitting the Apple store is a good thing as it provides more options. However, my only concern with it is that almost every review of it focuses on two phantoms used in stereo. So $4K (or $4.6K) rather than the $1.5K for the Mu-so. The only review of a single Phantom that I've seen was on What Hi-Fi? and they gave it 4 out of 5 stars because they felt it didn't really justify the price premium over the Mu-So. However, even that review is hard to judge because they compared the slightly more expensive Silver Phantom ($2.3K) to the Mu-So ($1.5K) making the price difference even more striking.

    When my electrostatic speakers died I went in to hear Magnepans as a replacement. I was ready to pull the trigger, but before doing so had a listen to the Mu-So. I was impressed. It has the Naim house sound. What is also useful about the Mu-So is it has good connectivity options. But then...I saw a Phantom in the corner. After hearing that I bought the Phantom and eventually sold off my entire system.

     

    The Spark software is a work in progress and connectivity options are thorough as the Mu-So, but that can be taken care of with with an Airport Express. I thought I was done, but then I returned the Phantom. I now have 2 Silver Phantoms in stereo. 1 is fantastic on it's own, 2 is better. I don't want to get into a debate about separates and value for money, but the Phantom has a sound I like and I'm happy to no longer be tweaking and seeing if things like power cords or other cables make a difference. In terms of the price, relative to the Mu-So, it depends where you are in the world and the exchange rate. For What Hi-Fi I would think the spread between the two is larger in the UK than other parts of the world.

     

    From my end I can now spend more time enjoying the music with a simplified setup. As development continues, while the Mu-So (and Phantom for that matter) may seem like a niche product today, the engineering, simplicity, and ability to just listen to music has the potential to push stereo components into niche status.

    I think products like the Mu-So and Phantom only seem like a niche product in the audiophile world. They seem exactly like the kind of product that is popular with regular consumers. Just think about how popular (somewhat similar) products such as Bluetooth speakers are becoming. The Mu-So and Phantom merely elevate the performance levels to more HiFi like levels.

     

    BTW, I regard the Phantom as a $4K to $4.6K product as it is really intended to be used as a stereo pair. So it's a far more expensive product than the Mu-So and really should be a proper upgrade in sound quality.

    Ah, well done. Thanks for giving some audiophile credibility to such a totally wonderful piece of gear. It is indeed quite a shareable, and awesome experience.

    I see a lot of people are confused about the product. I posted a review a while back, here http://www.computeraudiophile.com/f22-networking-networked-audio-and-streaming/review-naim-muso-25884/

     

    The answer to that question, really, is "a lot of fun in one very attractive, easy to use case."

     

    The sound was not perfect. It's single source (not stereo) and we found the top end a bit rolled off.

     

    But it was seriously fun. My girlfriend and I don't have a lot of overlap in musical tastes. We were struck by how much fun it was to construct joint playlists for the living room.

     

    If Naim could pull an Auralic and release a Muso without the amp and speakers at ~$500 I wouldn't hesitate.

    Wouldn't that just be a streamer? Why not just buy a Bluesound Node 2?

    Naim do have a Muso without the amp and speakers - its called the ND5XS but is more than $500. Its £2400. Equally just without speakers its a UnitiQute at £1300. Though they aren't identical as the ND5XS adds much more in the way of digital processing.

    I heard it a while back and it was very impressive. Pretty much ate my Sonos Play 5 for breakfast, lunch, and dinner.

     

    However, the pricing is a bit on the higher side and you can get separates for the same price for an actual stereo setup.

     

    As a convenience it is amazing, especially for the sound quality delivers. No more Bluetooth speakers provided you have the money.

     

    Still a bit late to the party, I see Chromecast Audio giving the same capabilities to pretty much any setup, including my 15-year-old hi-fi.

    I would say that it's really aimed at persons who value the compact form and convenience. If you are fine with putting a much larger and less stylish HiFi setup in your room, then there are no shortage of more traditional stereo options.

     

    If you want something far more discrete, but still sounds good and has modern connections then you look for products like the Mu-So. If you just want maximum sound quality for your money, then chances are that you would prefer a separates system.

    I did not find anything lacking in the sound quality, other than the fact that it was a single unit and so no stereo separation that comes from separates. But all said and done it's a Naim so performance is given.

     

    I would certainly consider it a serious upgrade over my Sonos Play 5, however I did not consider it seriously only because I will be auditioning the Devialet Phantom Silver Duo soon and considering the price to performance ratio (based on reviews) the Devialet looks to have the upper hand.

    Yep. The only real sound quality problem that products like the Mu-So may not be able to overcome is getting the kind of stereo separation of two distinct speakers (how much of an issue that is really depends on the individual).

     

    The Silver Phantom Duo should be a real step up, but it's also triple the price of the Mu-So. So it's really getting into more hardcore audiophile prices.

    Streaming may the future, but it is yet another way the artist gets screwed, and the consumer ends up not owning any media.

     

    Have a computer, just use AirServer or one of its ilk to have friends stream into your hifi.

    Please don't get me started on streaming. It's not streaming that's screwing artists, it's record labels. Sign a contract and you sign your rights away. Act as your own label, write your own songs, you'll make great money from streaming provided you release songs people like. Same as it ever was.

    Chris - Is the sound quality better or worse than Peachtree one, that you gave a rave review to? Your comments about sound quality, as opposed to aesthetics, seem rather tepid.

    I own a Mu-so. I can't quite understand why all the critical comments are being made about this unit,especially by those who haven't heard it. After all, it is intended as a single piece design, not separates. While it isn't inexpensive I find it worth the extra dollars over the less expensive competing products I have owned. I use Airplay to listen to uncompressed CD's i have in iTunes and Tidal.

    This item is not meant to be the final word in audio; it is meant to be a convenient package using more modern streaming technologies to provide above average results instead of using separates. It accomplishes this goal admirably. There is no way a serious audiophile would mistake this for a truly high end system but they will be surprised and pleased with this as a second or third system used to provide better than decent results, in a room where installing a larger system does not make sense or please the wife!

    I have placed some Stillpoint SS Mini's under mine and it sounds significantly better than before. It is being used for background music in my vacation home living/dining room. I am extremely pleased with it successfully fulfilling this purpose.

    Since I have a Devialet 200 in my office at my primary residence I did look closely at the Phantom. It wasn't the dollars that drove this decision. The Phantom is more of a louder rock out speaker, not such a refined sounding piece. Perhaps a future version of that will end up in place of the Mu-so someday.

    I picked up one of these yesterday after finding out about it from the 2015 awards thread (thanks!). Felt like I should throw out my impressions of it since this thread has such mixed feelings about the device.

     

    First, it's important to understand my intended use of the thing and my journey of finally deciding on the Muso. I had been wanting to replace the system in my home office for a while now. For many years I had a small headphone DAC/Amp hooked up via USB to the Mac on the source side and some "PC" sat/sub system on the other. I had looked at various things to replace this set-up. My requirement is that I needed a "bookshelf" sized system. I did not want to locate a sub. I did not want or need a bunch of traditional preamp features with a bunch of inputs. I'm about 85% listening to Spotify, Beats 1 Radio, or stuff my EDM DJ friends send me while I'm in my office. I do have my entire CD collection ripped and available on the NAS and that is played the other 15% of the time. My "reference" system is Vandersteen 3a sigs and 2x V2W subs in an acoustically treated room. I've got my listening room and I wan't trying to build a second one. I just wanted respectable sound in a package that would fit in my office and not be too silly complicated to set-up. In walks the Muso to my life...

     

    For clarification the Muso is a box that measures 24" wide, 10" deep, and stands 5" tall. It weighs a decently hefty 28 pounds, is encased in aluminum, has swappable colored cloth grills on the front, sits on an acrylic looking attached base which lights up the "naim" logo at configurable light intensities. Input sources include USB drive/iPods, analog, optical, and various forms of network streaming. It has built-in WiFi or hardwire ethernet. So far so good. This meets my requirements really well and the dimensions are actually pretty perfect for what I want in my office.

     

    My first listen was in front of the Muso naim display, in the middle of the audio store, streaming Apple lossless over BT from my iPad and sitting about 6 feet away. This was a store with dedicated listening rooms but they set their Muso display front and center of the store. Everyone in the store got to hear my eclectic mix of music. Not ideal but neither is my office environment.

     

    Very first impressions were a bit better than so-so. It goes much louder than I expected but stays very clean. It's a fairly neutral sound with maybe just a bit too much low-end while loudness is set to on (more on this later). That's the first setting I changed to off. The highs are a little bit lacking but what is reproduced is clear and decently placed. Listening in the store with loudness off I found everything that I threw at it was being reproduced in a very pleasing way with nothing feeling bloated or out of place. No real WOW factor here. Just clean music. My only complaint is that the midrange and vocals are a bit subdued for my liking. At no time, even with some female vocals that other systems struggle with, did this system "miss". It was spot on to the recording and reproduced everything that was there. I just like to have those vocals more forward than what the Muso was doing (maybe that's the "naim sound"? I don't know naim). Bass response was good, deep, and rolled off well before the dreaded bloat of a small system trying to do too much ever occurred. I was even impressed with how it handled the electronic music I sent it. My biggest surprise was that there _is_ actually some stereo separation and even a little bit of height and depth. You've really got to know your recording and be listening for it but it's there.

     

    After about 45 minutes my conclusion was that I could easily do better with separates if I was willing to give-up a lot of low-end or add a sub (which I didn't want to deal with). I could even spend a little less money than the asking price of the Muso by doing separates. Then the store offered me "black Friday pricing". That made it worth taking it home and giving it listen in its real environment.

     

    Here is where things get more interesting.

     

    I pulled down my old speakers and dropped the Muso in their place (about 7-8 feet on top of a bookcase). Now the highs were really lacking and it just wasn't nearly as good as sitting in front of it at the store. Time to rearrange the office. My office has bookcases on one side, desk in the middle, and a built-in cabinet on the other side that my printer sits on. I needed to find a place to get the Muso down to ear level. Time to move the printer. Then the WOW finally showed up. It is better than it ever sounded in the store. Final set-up is on a cabinet counter about 3 feet high and angled towards the center of the room where my desk is. Let's pause for a minute and talk about the 2 settings that affect how the Muso sounds.

     

    There is a room position setting in the app which lets you set "more than 25cm" or "less than 25cm" from the back wall. This setting significantly affects the highs and partially the way the Muso is presenting the soundstage. The other setting that affects the sound is "Loudness" which is supposed to increase the bass at lower volumes and then roll off that increase at higher volumes. I found that Loudness does a bit more than that and is, contrary to the documentation, affecting the highs ever so slightly. Now, there seems to be some magic that can occur by playing with the various combinations of these two settings. At the store I left the back wall setting alone but turned off Loudness and all my in-store impressions are based on that.

     

    OK, Muso at ear level about 11 feet away in the corner and angled towards my head in the center of the room. The highs are now back and significantly better than what I heard in the store. This required setting the room position to "more than 25cm" even though it is not. If this is set to less than 25cm the highs roll-off really really quickly. Almost as if someone keeps grabbing the cymbals after they are hit. Also, leaving this at "more than 25cm" raises the sound stage a bit. I've also turned on Loudness as this new position isn't bloating the lows so increasing the lows no longer has a negative effect on the balance of everything and really does help balance the sound at lower volume.

     

    With the new location and settings my impression of this system has changed a bit and for the better. It's now much better balanced and, while the highs are still not as good as I could get from a true bookshelf system, they are better. The highs are significantly better than any other all-in-ones I've heard. Just not as good as what this community is probably used to from "reference" equipment. I don't feel like I'm missing anything from the music other than space. The lows are powerful and room filling. Tight and balanced with the rest of the system. They are much much better than I could get from any bookshelf system I've ever listened to (without a sub). Naim really worked some magic here. The little bit of stereo separation that was there while sitting directly in front of it is gone now. This was completely expected. I'm not entirely sure I'd get much better with separates in my environment anyway. The slight depth and height of the music is still there though and this location has even opened up those vocals a bit and brought them forward which lessens my complaint from how I heard it in the store.

     

    Listening conclusion: Well balanced system needing only a bit more impact and volume on the highs. Mostly accurate to the recording (except for that complaint about the highs). No real stereo separation unless you're right in front of it and then only slightly. Wonderful depth to the music for such a small chassis. Wonderful liveliness and detail in every genre I throw at it. A really excellent system for my home office.

     

    Is it the ultimate in small room sound reproduction? No, absolutely not but so far I'm keeping it as it's pretty perfectly fitting into the environment I bought it for. The convenience of being able to send my music to it, without having to attach an Apple TV or Chromecast or some other dangly bit, is it's best quality. The streaming works great and sounds great right out of the box. It's well balanced to my ear which makes it pleasing to leave on for the, sometimes, 12+ hours I spend in my office a day. I've not found a genre that causes the Muso problems and that satisfies my eclectic playlists. It looks great as well which is generally something I never consider so bonus there. If the features and form factor are intriguing to you then go get yourself a listen. If you've got room for separates and already have a streaming solution then you could do better with those separates. If you want to pull something out of the box, set it down, and get into the music this is a really good set-up.

     

    If you do go have a listen I think its important to make sure you have access to the naim app. The two settings I mentioned do make a difference and they make a difference in a way that will be a listener preference so the store isn't going to set these right for everyone. Additionally, take it home and move it around. Placement makes a difference. That isn't surprising but maybe more important here because of how poorly the stores have this set-up for listening. Also placement plus swapping around the two settings requires a bit of trial and error unique to the Muso.

     

    Well, if you got this far thanks for reading and thanks to CA for including it in the awards this year. I'm finally working and listening happy again.

    Since thin is CA I should add a few notes or concerns:

     

    It will only stream 48kHz over WiFi so if you intend to use UPnP it needs to be hardwired to achieve the 24/192.

     

    This cannot be used as a DAC. The USB is expecting an iPod or a disk with folders and music on it. It does support a wide range of file formats up to 24/192.

     

    I don't have a tidal account but am impressed with its Spotify streaming so far. It's extracting as much as possible from that 320kbit stream. Even the radio station streams sound very well decoded. There is obviously a lot of processing going on but without anything sound "digital".

     

    WiFi is limited to b/g as others have commented. The WiFi reception seems OK. Could be better for having so much chassis though. Even with a "marginal" rating in the software I didn't have dropouts or issues though. Ethernet is limited to 10 or 100 mbit/sec according to the documentation. That just seems cheap to me. I'll plug it into a switch and verify but there is no reason to be releasing gear without gigabit transceivers. There is no mention if it support full-duplex either which is important on a streamer.

    It should support over 48kHz, its just not recommended for reliability. Have you actually tried higher or just repeating what Naim say? I think Chris reported 24/192 working via WiFi and I'm sure other people have done the same.

     

    This cannot be used as a DAC. The USB is expecting an iPod or a disk with folders and music on it. It does support a wide range of file formats up to 24/192.

    There is an optical input which supports up to 24/96.

     

    You are correct its 10/100 only ... but there is no need for Gigabit speeds for streaming audio and (I believe) Naim use 10/100 because they feel it is less noisy on the rest of the electronics.
