    Music Servers and Preamp Processors / Receivers

    front-thumb-1.pngThe numbers don't lie. Many music lovers can't afford a separate two channel system for audio and a multi-channel system for movies. Those of us knuckle dragging card carrying audiophiles have opted for the two channel system only while most civilians went the other way with a music and movie system in one. The system one selects is insignificant. Whatever enables one to enjoy this wonderful hobby of ours is just fine with me and should be just fine with all rational audiophiles. High quality music reproduction in the home can be accomplished with any well executed system. There are definitely less than stellar separates-based systems that sound vastly inferior to a well executed preamp processor or receiver. That said a well designed system of separate components is pretty tough to beat in my experience. Shortly after CES 2011 in January I started looking at preamp processors and receivers as an option for the computer audiophile without a dedicated system of separate components. I wasn't searching for a processor that could sonically better an equivalent separate component. Rather I was simply looking for a processor with several options for interfacing with a music server. I found the product I was looking for in the Marantz AV7005 Preamp Processor ($1,500 USD).

    <b>Marantz AV7005 Preamp Processor</b>

     

    First and foremost this is not a review of the AV7005. There are many other A/V sites that can give this product the full attention it deserves much better than Computer Audiophile. Plus I'm much more passionate about audio and interfacing music servers with high end audio systems. Writing a review about a topic or component that one is not passionate about is a recipe for disaster and is usually spotted by readers after the first few sentences. Thus I will share my experience and opinions about using the Marantz AV7005 in my system as a DAC and preamp processor connected to my McIntosh MC275 tube amplifier, Verity Audio loudspeakers, and a few different music servers.

    <b>Experience & Opinion</b>

     

    One look at the rear of the Marantz AV7005 and the average person would throw his hands up in surrender. There are so many inputs and outputs on this and all the processors and receivers that it can get quite confusing. I used four different digital input types and the L/R balanced analog outputs of the AV7005.

     

    <ul>

    <li><b>Ethernet UPnP/DLNA</b></li>

    <img src="http://images.computeraudiophile.com/graphics/2011/0512/dlna-logo.png" style="padding: 5pt 10pt 5pt 5pt;" align="left">Of all the inputs I was most excited about the AV7005's Ethernet DLNA/UPnP capabilities. I was ready to send multi-channel audio and all kinds of high resolution two channel music to the unit from a Windows based computer. It turns out I was a bit too optimistic. I used Windows 7 with J River Media Center 16 to send audio over Ethernet. JRMC automatically recognizes the Marantz AV7005 as a DLNA/UPnP renderer capable of accepting audio via Ethernet. The AV7005 simply appears as a separate Zone selectable on the left side of the screen. Once the AV7005 is selected the user browses and plays music as if it was being output to a directly connected DAC. Mac OS X DLNA/UPnP software is way behind the capabilities of J River Media Center. Knowing this ahead of time I opted to try Windows only for DLNA/UPnP playback. This Windows / JRMC 16 combination sending audio via Ethernet worked well for the most part. Every once in awhile I would lose my connection to the Marantz processor within JRMC. To regain the connection I simply had to reselect the AV7005 within application. I can't say whether the problem originated from JRMC or the AV7005 or both. My guess is the AV7005 was the problem as I've used JRMC many times via Ethernet without this problem. One additional reason I recommend using Windows based servers when sending audio over Ethernet to the AV7005 is this processor's lackluster <a href="http://images.computeraudiophile.com/graphics/2011/0512/dlna-formats.png" class="thickbox" rel="dlna-formats">support for codecs and sample rates</a>. FLAC is the best format to use with the AV7005. Both 16 and 24 bit music with frequencies from 32 kHz through 96 kHz are supported only when sending FLAC files to the processor. WMA, MP3, WAV, and AAC are all limited to 32 kHz through 48 kHz playback. Multi-channel playback is a different story. I purchased several tracks from the Laurence Juber Guitar Noir album in every possible multi-channel format available from Mark Waldrep's iTrax.com website. The only multi-channel files I was able to feed the AV7005 over Ethernet, and have the processor actually read as multi-channel, were 16 bit / 44.1 kHz <a href="http://images.computeraudiophile.com/graphics/2011/0512/dts-UPnP.png" class="thickbox" rel="dts">DTS encoded WAV files</a>. Other multi-channel files were read as two channel by the AV7005 or as unplayable because the processor doesn't accept 24/96 WAV files. I did convert some of these WAV files to FLAC in an effort to play higher resolution multi-channel music but I was just as unsuccessful. In addition to sending music to the AV7005 from a PC the AV7005 can also pull files from a UPnP server like Twonky or Asset UPnP. I spent about ten minutes browsing my UPnP server via the front panel before deciding it was the absolute last way I would use the AV7005 to play music. I did connect a display to the AV7005 briefly but I still consider the interface for pulling music to the unit is less than good.

     

    <b>Overall</b> I'd say two channel playback over Ethernet DLNA/UPnP was good in terms of usability. Certainly not flawless or great but not bad or unusable. Simply good.

     

     

     

    <li><b>Ethernet Airplay</b></li>

    <img src="http://images.computeraudiophile.com/graphics/2011/0512/airplay-graphic.png" style="padding: 5pt 10pt 5pt 5pt;" align="left">The Marantz AV7005 is advertised as AirPlay compatible. This means the unit is not AirPlay ready right out of the box. AV7005 users must upgrade the firmware then purchase the $49.99 AirPlay package directly from the Marantz website. The actual upgrade and package installation is simple and takes about 40 minutes all together. Based on my experience using the built-in AirPlay implementation of the AV7005 I do not recommend it to anyone. I tried sending music from my MacBook Pro with iTunes and directly from my iPhone 4 to the AV7005 using AirPlay. No matter what I did the audio was choppy with dropouts and frequent complete disconnections playing 16/44.1 material. The Marantz AV7005 was wired to my Gigabit Ethernet switched network as was my MacBook Pro during my tests. This network performs very well for all other streaming including via AirPlay to an AirPort Express as discussed below. I talked to one manufacturer about AirPlay a few weeks ago and was told that AirPlay is far from a finished product from Apple. There are many implementation issues for third party manufacturers trying to incorporate this into a product. If my experience is any indication of what's to come I suggest waiting for the second generation of AirPlay devices unless one can thoroughly test the product in one's home.

     

    <b>Overall</b> I'd say the built-in AirPlay capability is not ready for prime time.

     

     

     

    <li><b>Optical S/PDIF (TosLink)</b></li>

    <img src="http://images.computeraudiophile.com/graphics/2011/0512/airplay_callout-1.png" style="padding: 5pt 10pt 5pt 5pt;" align="left">The optical input of the AV7005 worked as expected while connected directly to a Mac Pro running OS X 10.6.7. No issues playing stereo content although the optical output of Macs is currently limited to 96 kHz under OS X. Because I was still interested in sending audio to the AV7005 using AirPlay I connected an AirPort Express to the processor via a TosLink to Mini-TosLink cable. This method worked like a charm every time. I highly recommend AV7005 users spend $100 on an AirPort Express, instead of $49.99 on the AirPlay upgrade package from Marantz. It's long been known the AirPort Express does not support high resolution audio. With this in mind I thought I'd play some high resolution 24/96, 24/176.4, and 24/192 music anyway to see what happens. I was able to play music at all the aforementioned sample rates without a hiccup however, as expected, the MacBook Pro / AirPort Express combination only sent 16 bit / 44.1 kHz audio to the AV7005. This was actually a very good thing for fans of playlists. Some DACs don't play a single note when an unsupported sample rate is sent to the component. This silence is often unacceptable when running through a multi-sample rate playlist while party guests are enjoying the music. Using the AirPort Express with AirPlay allows the music to keep rolling albeit with less sound quality. When using an AirPort Express with AirPlay I'd much rather have music playing even if it's downsampled to 16/44.1. I don't expect an AirPort Express to set the high end world on fire in terms of sound quality so I don't use it for serious listening anyway. Sending audio straight from my iPhone 4 via AirPlay and AirPort Express worked without issue as well.

     

    <b>Overall</b> using an AirPort Express instead of the built-in AirPlay capability was very functional and worked great. No unforeseen issues. The combination worked as designed.

     

     

     

    <li><b>Electrical S/PDIF (Coaxial)</b></li>

    <img src="http://images.computeraudiophile.com/graphics/2011/0512/spdif-coaxial.png" style="padding: 5pt 10pt 5pt 5pt;" align="left">Going into this AV7005 <s>experiment</s> endeavor I had high hopes for the S/PDIF coaxial input. I hoped it would support all the common sample rates and sound good. Fortunately both of these hopes came to fruition. I used a Mac Pro in combination with a Wavelength Audio WaveLink asynchronous USB to S/PDIF converter to connect to the AV7005's coaxial input. The cables used in this combination were a three meter <a href="http://images.computeraudiophile.com/graphics/2011/0512/ww-p-sl.jpg" class="thickbox" rel="ww">Wire World Silver Starlight USB</a> and a three meter AudioQuest Eagle Eye 75 Ohm BNC Digital Cable. Sending audio to a DAC or preamp processor using a USB to S/PDIF converter allows the user to ignore the processor's supported file types (WAV, AIFF, FLAC, etc.) unlike sending audio via Ethernet DLNA/UPnP. The playback software already converts the encoded files such as WAV and FLAC to straight PCM before sending it out the computer's USB port. What matters for playback are the sample rates supported by the S/PDIF interface(s). Using iTunes with Amarra 2.2 and Pure Music 1.74a, while hiding Pure Music's Music Server Controls (?H), I played files from <a href="http://images.computeraudiophile.com/graphics/2011/0512/coax-44.png" class="thickbox" rel="16-44">16/44.1</a> through <a href="http://images.computeraudiophile.com/graphics/2011/0512/coax-192.png" class="thickbox" rel="24-192">24/192</a> with absolute ease. I really liked the coaxial S/PDIF input on the AV7005. I highly recommend using this input if at all possible. The combination of WaveLink and AV7005 act exactly like every other DAC discussed here in the Computer Audiophile forums. The only important configuration change one must make is setting the processor to Direct Mode. This bypasses all Digital Signal Processing that is designed to change the sound by design.

     

    <b>Overall</b> this is the best sounding and most functional digital interface on the Marantz AV7005. It's the only interface I would use for serious listening.

    </ul>

     

     

     

    <b>Final Thoughts on Using a Preamp Processor or Receiver</b>

     

    The first thought that comes to mind as I think back on my use of the Marantz AV7005 preamp processor is it's a jack of all trades and master of none. This type of component isn't typically what audiophiles use when going for the absolute best sound quality. Rather this type of component is used where most of its capabilities are needed. It's a cost effective way to meet the needs of the music lover and movie buff. As I said in the opening paragraph, I couldn't care less what components one uses to satisfy one's musical needs. In a pinch I'll take Pearl Jam's Vitology album through an AM radio. It's the music that produces a good feeling in most people. Accepting compromised sound quality isn't something I prefer when I have a choice. I'm not usually in an AM radio requiring pinch or in a position that requires the use of a preamp processor or receiver. Throughout my listening sessions with the Marantz AV7005 I compared its sonic qualities to the Bel Canto DAC 1.5 ($1,395) and the Berkeley Audio Design Alpha DAC ($5,000). In all comparisons with all music the AV7005 could not compete with the DAC 1.5 or the Alpha DAC. The AV7005 smoothed out all music and removed all transient slam from every recording I played. The preamp processor contains very capable internal components but way too many of them to implement at a high level for a reasonable price. Even if the design team had an unlimited budget and no target price it's entirely possible that such a component simply is not capable of besting well designed high end separates. Computer Audiophile readers thinking about going the preamp processor or receiver route instead of separate components should think twice or three times before spending any money on such a component. CA readers without the option of separate components should be happy knowing they can, at a minimum, become computer audiophiles by connecting a music server to a preamp processor or receiver using one or two of the many connection options available.

    So far, all my rips of DVD as archival info are direct to the on board hard drive… IF I feel it is a ‘Keeper’ (7/10 or above rating) I’ll copy it to another drive, likely a NAS so any machine can access the file. Unless it’s a BR disc. I’ve not yet found a suitable method for copying BR formats…. Nor will I likely bother to.<br />

    <br />

    All the machines I have but one, use Cyberlink. The laptop uses a combination of either Windows Media, or JR MC 15. Depends primarily on which one likes the copied content. I say it that way as sometimes despite the decryptor the software can be stubborn.<br />

    <br />

    90% of the time, playing movies I’ve placed onto the NAS work fine… wirelessly, or by Ethernet. Once in a great while I get a error message indicating the dVD is the wrong region …. I don’t use zoned material outside of my region. Ever.<br />

    <br />

    So that flag is erroneous. Albeit, playback is refused.<br />

    <br />

    My real ire comes from the DLNA declaration on some appliances that simply do not support TS or VOB files per se… and want one to convert them into avi, Divix, wkv, etc or some other format… and have them on a particular formatted disc… FAT; FAT 32; and just lately, NTFS.<br />

    <br />

    Archiving DVDs for my purposes is an exemplary method for cataloging and selecting films for playback. Playing these films back on my Panic sonic TCP 50C2 720p Plasma, I’ll use my oldest pc with the aTI Radion 1.3 HDMI card, which oddly enough I can not elicit Blu Ray playback from although I have a very recent Plextor BR drive installed…. That issue seems to revolve around the Cyberlink software which of it’s own accord says some issues exist in the environment preventing BR playback… although each reported instance of non compliance can be refuted properly. So.. all the hardware and so forth meet or exceed the DHCP standards, but the software says “Sorry… No dice!” as it does with errant or untrue flags in other instances.<br />

    <br />

    Amazing.<br />

    <br />

    So SD DVD playback off my personal confusers is all I can expect currently. No Blu Ray. I’ve given up on achievinfg BR replay from a confuser… within or out of, it’s environment.<br />

    <br />

    I’ve given up on DLNA too other than streaming online video and audio from joints like Slacker, VuDu, Netflix, and a couple others.<br />

    <br />

    All of which, I must often administrate via a desktop or laptop then select from the OSD presented by the display. Otherwise, go set up the queue by pc, and then merely pick from the existing lists as shown by the player on the plasma display. Naturally these measures are the result of my own personal physical challenges and not the limitations of the hardware.<br />

    <br />

    Lately I’ll merely view what ever content over or off of my comfusers. I won’t bother to fire up the projector and main rig for sure or even the second system… if it’s just me …. It’s too much bother and and a waste of energy.<br />

    <br />

    Such is life in a world where people reside on the bleeding edge of technology…. It is frought with pittfalls. Blazing new cyber trails one can indeed, wind up with a butt full of arrows. <br />

    Yep - I sympathize brother. I have a whole bunch of DVD's I made of my own work (iMovie + iDVD), as well as other footage I wanted to get quick access to, not so much films or other commercial DVDs. <br />

    <br />

    The little WD unit, even though it has its own storage, attaches just fine to DASD published on the network, and has auto-sync capabilities on it. I also acts as a DLNA Library and Renderer, though getting those capabilities to work together is interesting. <br />

    <br />

    For $100, you might want to check it out and see how close it comes to meeting your needs. Fighting with PC's and Windows and the software that runs on them is sometimes just a loosing battle. In this world, playing back VOB files that is, Macs don't seem to be any better either.

    If Chris prefers a Dac with a Pre into a power amp the Naim Uniti might be worth a review. It sounds wonderful, can be used with power amp (Nap 200), works as an ipod digital dock and in my case a sublime flacrenderer using my Vortexbox server as source. For the more cash rich adding an NDX to the mix would up the stakes considerably.<br />

    <br />

    How about it Chris - Naim Uniti review to compare to the Linn DS-I review of a few months back?<br />

    <br />

    <em>"Quite frankly, I don't understand why the Marantz is being reviewed here. It is like a website dedicated to roadsters reviewing a SUV and complains it doesn't corner well."</em><br />

    <br />

    Hogwash and balderdash, says I. I for one am appreciative of this unreview as it just saved me a bit of heartach. I almost bought one of these preamps! I mean, I still might, but I'll now be looking to front it with an external DAC if I do.<br />

    <br />

    Chris, did you mention how the unit sounds --> as a preamp alone? That is, how's it sound when fronted by a DAC you're familiar with instead of using that other external DAC into a different preamp you're also familiar with?<br />

    <br />

    Also, any luck with the Pandora feature set? I am especially curious about that as well ....

    It is just as valid to do a "review" or write up about this unit as it is any other DAC especially the lower end DAC's that are good SQ for the price. I for one happen to use a much higher end Pre Pro for a DAC and have been very pleased with the sound.

    ...and come housed in really big boxes surrounded by tuners, switches, interfaces, etc. and get called processors.... but 90% of what they do goes thru the on board DACs.<br />

    <br />

    The funny part of this is right off the bat, Chris said this should not be considered a review fo the Marantz proc... in his first paragraph. <br />

    <br />

    how one can not preview this article without drawing some ideas from it as a review of sorts however does strike me as being funny given the statement opposing that notion early on.<br />

    <br />

    Maybe it's just a spec sheet check for errors, and on the spot config setups. <br />

    <br />

    Whatever the case it actually is... it has revealed some important items. <br />

    <br />

    OK to Good was the subjective quantiziation of the sound quality, as stand alone, or fed by outside sources.<br />

    <br />

    So buy one or don't. Wait and see for more Networking and streaming solutions, or scoot on n and dig this bill of fare.<br />

    <br />

    All in all... for $1500 cold hard U.S. duckets.... wadda ya want?<br />

    <br />

    I've spent half that much on my proc and don't use it for any extraordinary decoding of streaming audio or video... and am well pleased.<br />

    <br />

    Facts are so far from my perspective, none of these DLNA passports are ready for every file... every bit rate ... or prime time.<br />

    <br />

    So let the personal confusers do what they do best, and maybe someday the home theater processor will indeed be a home theater processor which can process all aspects of home entertainment.<br />

    <br />

    Even Computer Audionuts, own stuff besides their confusers... and if I see a couple things that are not connected I like to connect them, when feasable....just to see what's up.<br />

    I personally gave up on using a currently produced AV processor or DVD drive as a decent 2 channel audio server.<br />

    I think the ability of one of these devices to better a computer driven DAC as a server is just too far away currently. Certainly there are the Auraliti, Bryston, and many other good music servers with all or part of an inboard computer running them, and I hope to use of these to detach my computer from the system at some point.<br />

    <br />

    I might end of with one of these AV processors though for other type of system you mentioned : the concurrent 2 channel and multi channel setup. I hope to use the "bypass" function of my pre to use my main speakers for part of a multi channel system to play movies in my man cave, and perhaps some multi channel music as is available.<br />

    <br />

    After reading this set of comments I did learn that the Oppo 95 I am using occasionally for SACD and CD might function as a DLNA server also. Might be worth experimenting with. I doubt it will beat the Mac - USB - W4S Dac2 though. An experiment ultimately.<br />

    <br />

    Its good to see discussion of this topic progress. Thanks again.

    Accustic Arts added a "SURROUND BYPASS" input on their integrated POWER-1 Mk2.<br />

    This means, you can use the stereo-highend-system as front amp & speakers and complement it by a much cheaper surround system. Volume control of the POWER-1 is disabled then, you use the volume control of your surround receiver. You not even need much power for the front speakers, cause you use the pre-out of the receiver to connect to the surround bypass.<br />

    <br />

    It's a shame, I only own the Mk1 :-(<br />

    <br />

    And the separate AA PREAMP-1 offers the same input - for surround lovers! B-)<br />

    <br />

    Maybe other brands share an identical feature!?

    Nice review, one that highlighted many of my frustrations in dealing with integration of dedicated two-channel hi fi and surround applications. Two separate systems, or one with sacrifices??<br />

    <br />

    I think it is possible to have both in the same system without giving up anything. While one could spend exorbitant sums on a well designed pre-pro that would perform well in two channel applications, the problem is that the surround industry moves fast and you might be compelled to upgrade more frequently than is monetarily practical. Affordable receivers or pre-pros, while fine for surround, are unfortunately inferior in two-channel audio reproduction in my opinion. I became interested in finding a way around this, which I think I have successfully accomplished.<br />

    <br />

    Many products, including my PS Audio pre-amp, have "HT bypass" inputs, effectively inputs that are locked in unity gain allowing use of an external volume control. One needs only to only find a reasonable surround receiver with pre-amp outputs and run the main left and right outs into these inputs. The receiver drives the center and surround channels. I have been using a Denon receiver for sometime in this way and have been more than pleased with the surround quality, while not losing anything as far as the two channel experience goes.<br />

    <br />

    I couldn't agree more with other comments on the additional frustrations of using DLNA devices. The Denon receiver noted above has this functionality, one that I tried using for years to serve music files from a home server. Not reliable, and the sound quality was terrible. Based on this site, I just put together a media PC with J River Mediacenter which solves this problem. The sound quality through a Rega Dac is the best I've heard in my listening room, a quantum leap over an old Cary CD-308 disc spinner. Not only do I get a substantial improvement in sound quality, but the functionality of the media PC is superior, and I have the option to run multichannel audio to my receiver via HDMI.<br />

    <br />

    Anyway, nice review and great website.

    Chris, Thanks for the review. I just bought an AV7005 in an attempt to merge a 2-channel and ht set-up to maximize the sound quality per unit of audio boxes. At one point I had high hopes for getting rid of my W4S DAC2 and going straight into the digital input of the AV7005. Now it looks like I'll be using the ht-bypass of the DAC2 for any serious listening. <br />

    You ought to try to get hold of the new Harman-Kardon HK-990 Stereo Integrated amp. What a piece! 150 BIG Watts/channel (separate power supplies - including transformers - for each channel able to supply ± 200 Amperes), built-in dual differential DACS that will do 24/192 and up-convert lower rez to 24/96. It has built-in ADC for recording analog sources to digital. Built-in phono preamps for both MM and MC, and a room equalization DSP setup complete with calibration microphone and all for $2500. Sounds great, works well, has more I/O than you can shake a stick at. Any input (except phono) can be either digital or analog or both giving incredible flexibility. I was so impressed, I bought one. Replaced my much-loved VTL 140 tube monoblocks, my AR SP-9 Mk II, my Sonic Frontiers DAC3/D2D up-converter with one and haven't looked back.

    I have an Arcam AVR 600 that I've compared with medium priced separates and it truly holds its own in terms of musicality and bass. It is however more expensive than the Marantz so maybe that isnt a fair comparison.

    Great Write up but out of curiosity why not review the NA-7004 network player?

    Hi Chris,<br />

    <br />

    Just discovered your site after getting back into the high end audio.<br />

    <br />

    I got out of the high end over 10 years back for economic reasons as well as the frustration over CD reproduction. I became an audiophile during the early 1970's and went through the Linn LP12/Gales/Accuphase experience, Accuphase C280/M100's Gales and Michel Gyrodek, settingling on Electrocompaniets and Proac speakers using the gyrodeck/SME V combo with Ortofon moving coils. I also sold Hi Fi during the early 1980's and was there when CD's arrived. Been there, done that, as they say.<br />

    <br />

    I got back into the high end over the last 1/2 year after I realised that music was being delivered as computer files. Only when I discovered Naim and Linn (and RR) were selling high res files, 24/176.8 did I start becoming serious. Being computer literate also helps, (I was working with mainframes during the 1970's), and I quickly realised that a decent digital soundcard and dedicated computer would be the preferred solution.<br />

    <br />

    I mentioned this to a friend in the Perth, Western Australia Hi Fi wholesaling business (he's the Accuphase importer) and he told me to read the latest Stereophile. I did and it got me up to speed.<br />

    <br />

    I run a Windows 7 computer (Sony Vaio all in one unit) outputting usb and optical. I had already bought a Musical fidelity M1DAC to feed the Lehmann Black Cube Linear and Sennheiser HD800's, and was resigned to the fact I had to buy another computer that could take a standard sound card. As if I needed another computer, using the HP Z400 workstation for my professional work, and Toughbooks for fieldwork (I am a field exploration geologist). Stereophile Mag opened my eyes and I spotted the Bryston BDP-1 digital player.<br />

    <br />

    My existing set up is the Sony Vaio, Denon DCD2000 AE SACD player, Tivoli Networking digital radio with second speaker/subwoofer, (I live in a trailer or caravan as we call them here), powered by a 500W inverter using the RV battery supply.<br />

    <br />

    Once I realised the Bryston BDP-1 was basically a sound card and computer system, without all the unnecessary inputs other solutions offer, I bought one. I also bought the MF V-Link to play the large number of sound files I had collected over time on the computer.<br />

    <br />

    Your website was instrumental in getting me back into the High End, and as I mentioned to my friend, we are back into the old high end audiophile times, when then it was choice of phonograph cartridge etc that was important in accuracy of reproduction.<br />

    <br />

    Now it's about DAC's pre DAC's (V-Link).<br />

    <br />

    I do enjoy reading your reviews and also the informative comments put by your readers.

    I have a Marantz AV7005 and AV7055 power that I bought a few months ago. I have an Oppo BDP-83 SE player too and now I intended to go towards a computer audio, besides the Airplay and the Toslink Macbook conection that I currently use.<br />

    In yours review you told that liked AV7005 and USB/SPDIF Wavelenght combination, but don't compare to a Bel Canto 1.5 in terms of quality and audio details. My question is: Use a Bel Canto 1.5 connected to AV7005 via SPDIF give me something more than the way you have tested?<br />

    The NAD receivers with their true analog bypass (all circuits that are not needed are shut down)should not be forgotten. I use my 775 HD as a preamp for music. The DAC's in the NAD are no slouches in line with NAD's "sound first" motto so the receiver could very well be used as the DAC as well - at least to start with. I have a Bel Canto 1.5 going through the receiver (used strictly as pre-amp) and then on to an external amp. Now the NAD also has excellent amps. so the flexibility is pretty endless.

    My attention was also perked with the Ethernet protocol. I havent read anything Ethernet related, its all USB this and that. <br />

    <br />

    I have been happy with one of the few, dare I say only "real" option out there for audio over Ethernet - being the Squeezbox variety. I love it. Its tweaky at times, needing to "log on" and all. There are work arounds for the quirks. I love the "cable independent" "bit perfect" nature of Ethernet. Hand shaking and all that good stuff. It makes me appreciate how hard it is to get the hardware and software thing right with Ethernet. Go Squeezebox!

    After many years of compromised music listening on my 7.1 Ch HT system, I added a pair of Paradigm Sudio 60s closer to my sweet spot than the HT speakers which were 16 ft away flanking my 8' x 4.5' movie screen. The 60s are 12' away with plenty of rear and side space, nearly opitmal triange, and are driven by a separate 225-watt amp instead of AVR. Wife not so pleased but I'm a very happy camper, especially listening to HiRez stereo audio!!!

    Hi Chris,<br />

    <br />

    Sorry for picking up this old post. <br />

    <br />

    Can you list out the companies that uses ravenna chips/technology in their DACs? <br />

    <br />

    I'm very interested in the Ethernet connection for DACs, but seems limited choices are available in the market. <br />

    <br />

    Thanks!<br />

    Here is a link to Ravenna partners.

     

    Genelec (speakers) had already in 2010 a demo in an audioshow.

     

    link: Genelec Active Speakers Offer Simple Audio Over IP Package (ISE 2010) ... e-ise-2010

     

    And here is a link to an excited guy from Merging Technologies (2011)

     

    link:

     

    Personally . . . I am waiting for a "consumer line from Genelec with IP connection"

     

    Anyone else interested in this ?
