    LessLoss Echo’s End Reference DAC Full Review

    Louis Motek, aka, Mr. LessLoss, aka, the German speaking Lithuanian daredevil of HiFi was at it again. Nodding to the classic salesman line, “Do you feel you’re missing something? Do you feel there’s more? Do you ever wonder what could be? If you answered yes, then I’ve got something for you…” Yet again, I fell prey to his works of wonder. Already smitten with LessLoss – as many of you know, I own several of his C-MARC power cords, a C-MARC S/PDIF digital cable and the stupendously fabulous C-MARC custom phono cable – I frankly couldn’t resist the temptation. Yet another new toy to explore and play with? Why not. Louis’ surprise email exchange finally brought to life his ask: if I was interested in reviewing his latest digital offering, the Panzerholz enclosed and thusly bulletproof LessLoss Echo’s End Reference DAC.

     

    LessLoss-EchosEnd-_FON3891-1000px.jpgA remarkably clean, no-nonsense sort of Panzerholz enclosed box arrived shortly thereafter in a sturdy flight case. Did I mention Echo’s End Reference is enclosed in Panzerholz? In case I missed it, I’d like to remind you that Echo’s End Reference is built around a super solid and bulletproof case of Panzerholz. Louis has a fascination with Panzerholz. Inert, damped and built to last several lifetimes, not to mention resist several bullet blasts, he first doodled around this wonder material whilst becoming friendly with the fine folks at Kaiser Acoustics. Exclusively built around Panzerholz enclosures, Kaiser Acoustics has developed a formidable, nay, legendary reputation for producing some of the very best loudspeakers in the market today. Add Louis’ minimalist vision to the mix and you are presented with a sleek, firm and nondescript box containing a pair of left/right R2R ladder DACs and LessLoss custom, proprietary add-ons, power filtration devices, C-MARC point to point wiring and many other very high-end custom bits and bobs. Never one to shy away from showing off his skilled, bespoke craftsmanship, the enclosed pictures tell the visual story. Delightfully executed, built by hand, one DAC at a time, this has to be among the finest built bespoke digital converters out there. Beauty, in this case, is indeed skin deep. Given all this artisanal craftsmanship, I, for one, do not feel as though this DAC asking too high a cost factor. Frankly, there are multitudes of multi-box solutions out there that cost similar, yet at least on Saville row, offer far less elegance. 

     

    And yet, all together, this has to be the most non-remarkable looking DAC I’ve ever laid eyes on. Friends visiting chez K these past few months didn’t even notice it. So subtle are the design cues that with the DAC placed on my Tabula-Rasa solid wood rack (sadly, not made out of Panzerholz…), it almost looked like a jewel box, or a cigar box, or even an heirloom – not a DAC selling for a click less than $20k. The newly arrived Playback Designs MPS-8, even my trusted AURALiC Vega G2, at least appear to look like digital audio converters in today’s design language terms. While the Vega G2 boasts a unibody CNC machined from aluminum block case, the Playback Designs MPS-8, a gorgeously sculpted – perhaps the finest looking design theme in HiFi today – also CNC cut from solid aluminum block, chassis, both have a defined appearance of representing some sort of HiFi component, especially so the MPS-8, which also boasts a CD tray. Echo’s End? Clearly not designed to compete on visual terms with either of these DACs. 

     

     

    LessLoss-EchosEnd-_FON3756-8bit-1000px.jpg

     

     

    Further separating Echo’s End from the competition is the fact that this LessLoss machine is a DAC, and a DAC only. Reminiscent of my EINSTEIN The Last Record Player, CD player, also just that and nothing else, the LessLoss provides four inputs of the digital variety: USB, AES, S/PDIF and BNC. That’s it. The output end is equally sparse, with left/right balanced and single-ended outputs. A standard IEC power receptacle completes the I/O for Echo’s End. No other buttons, switches, lights, are visible on the Panzerholz case. Nada. Nothing. Zilch. Tote Hose. No wonder people don’t recognize it for what it is; they recognize it for all the things it isn’t. Ain’t that funny. Then again, I dare say a typical sort of LessLoss-y type product. Kein Firlefanz. 

     

    The ladder DAC inside supports hi-res PCM and up to double-rate DSD; all switching between inputs is done automatically; i.e. the unit automatically recognizes which input to switch to and voila, off to the races you are. Having long ago switched my digital playback library to Roon power by Roon Nucleus via my 32TB QNAP 8-bay NAS, I really have no need for a dedicated (or otherwise) MacBook to act as a classic source component. Both the AURALiC and Playback Designs accept ethernet inputs and thusly act as Roon endpoints, which removes a whole bunch of futzing with this that and the other. That said, to test the USB input of Echo’s End, I simply ran my USB leashed MacBook Pro acting as Roon endpoint. While I had to manually configure the newly visible generic DAC, for optimal performance, neither Roon, nor the MacBook nor Echo’s End showed any signs of trouble whilst sorting through thousands of standard and hi-res PCM and DSD files. MQA’d Tidal files? No problem, given the first Origami unfold was handled by Roon / MacBook Pro anyway. Newly acquired and hi-res Qobuz files – needing no conversion anyway – played equally fine and without any hitch.

     

    LessLoss-EchosEnd-_FON3751-8bit-1000px.jpgRigged up to playback system one, itself consisting of EINSTEIN The Preamp and The Silver Bullet Mark II OTL amplifiers, driving Wilson’s Alexx, and EINSTEIN’s own The Loudspeaker (*superb indeed), musical bliss was virtually guaranteed from the first note. On first listen and without a doubt, Echo’s End Reference follows the clear sound path set forth by everything I have auditioned from LessLoss going back to the mid 2k’s and their first DAC product: organic, authentic, resolved, dynamic. No matter the cut’s to be transcoded, the sonic signature was virtually the same. Echo’s End seems to echo the enclosure – Panzerholz – quite to a T, or perhaps more likely, a P. Trentemøller’s Evil Dub, off his 2006 release, The Last Resort, is anything but a simple, ProTools produced track. Here, the artist is weaving in and out of thematic, propulsive, nay, explosive bass lines, intertwined with playful phase effects that ought to give any system a proper workout. Whereas some digital systems favor a more spotlit presentation, cueing the listener into each of the themes, Echo’s End presents you with more of a stage view, which is to say you are listening to the entire production rather than drawing your focus to and from each note and phase effect. 

     

    This same sonic signature can easily be heard on symphonic orchestras, quaint quartets and trios, jazz cuts or really any other genre. On a Star is born, the soundtrack to the film, Lady Gaga performs several cuts well above her normal repertoire. Not a big fan – in fact, no fan at all – of her overproduced dance pop productions, here, she transforms herself to a genuine artists and female vocalist of the highest order. Of course, having a virtually unlimited production budget, given the blockbuster status of the motion picture, tends to produce quality work even if that work ends up being dramatically commercialized mass marketed bubblegum pop music. Half-way through the album, track number some such or another titled “Is that alright”, shows Lady Gaga accompanied by only a solo piano. While the track is drenched in schlacky reverb from beginning to end, the production quality, as juxtaposed as it may seem, is rather masterful. It’s really a shame that most of the folks who listen to this soundtrack will likely never hear it in all its faux glory, because in the end, it actually really sounds damn fine. Through Echo’s End, this presentation is far more than lifelike: the producer’s intent never was to have Lady Gaga performing in your room – quite the opposite, it was to have you, the listener, brought to Lady Gaga’s. Cinemascope-y in sound, scale and sense, Lady Gaga becomes larger than life, enveloping you into the mix start to finish. That organic, natural and neutral sonic signature of Echo’s End plays fantastically well with this type of a recording. Where the Playback Design’s MPS-8 is far closer to that presentation, AURALiC’s Vega G2 moves the curve the other way, highlighting the leading transients and giving the entire image a more edgy feel. 

     

    Next, I wanted to take to EINSTEIN’s The Last Record Player, my trusted CD source. Here, a simple leash via LessLoss’ C-MARC S/PDIF cable, proved that system synergy really is a thing. The EINSTEIN does one thing and one thing only rather well: it plays my CDs, in sync with the rest of EINSTEIN’s house sound. Wide open, dynamic, punchy and with just the right amount of sweetness, this player’s hallmark is how it transforms simpleton CD sound to almost hi-res like status and quality. The only other deck that did / does the same, though taken to even more realism, is Andreas Koch’s Playback Designs MPS-5 of yesteryear, and the all new MPS-8 of today. Dog, man and leash in hand, Echo’s End proved once again that no matter the input and source, this DAC’s sonic signature stayed the same. A habit of late has been to acquire the CD version (and LP) of any new music I purchase; thus enabling me to have at least a 16/44 hard copy on hand. Similar to my findings with the MPS-8, I have come to realize that no matter the quality of the stream via Tidal or Qobuz, the actual, physical medium – in this case, 16/44 redbook CDs – always sound better than either stream source. Simply put, both the EINSTEIN and Playback Designs disc players perform at far higher quality levels when spinning discs. Streaming from my QNAP’ed NAS via Roon’s Nucleus is a close second; then followed by Roon’d Tidal/Qobuz. I have done this comparison time and again, with results that are very similar. Only when I play hi-res MQA or Qobuz PCM files, does the delta begin to shrink and in many cases exceed the CD quality heard through either disc player. Echo’s End further helped clarify this with its organic character highlighting just how good, nay, great, good old compact disc can sound.

    In the end, what does it all mean? Frankly, to me at least, this LessLoss DAC is a bit of an enigma in today’s market place. First, it’s expensive, at $19,628 USD. While the build quality, internal makeup and parts quality are undoubtedly first rate, it begs the question of just who this DAC is for. Show-off’s and luxury, diamond studded watch aficionados need not apply. Here, the bling factor is practically nil. No fancy case work to show off, no lights to dim or displays to distract. Echo’s End is a beautifully made, wooden box, sitting atop your rack. It transcodes digital to analog, that’s it. It does so in a manner exclusive to the philosophy of LessLoss. As their name implies, less loss by definition implies more musical information, detail retrieval and texture. Editorializing isn’t part for the course. What you hear is what you get. Once you bite off the LessLoss tree, you may not look anywhere else – my personal ownership of their C-MARC based cables proves the piped point. Reference quality in every regard. 

     

    Yet, in today’s market, and even with all these accolades, that’s a tough sale, not that LessLoss is seeking to raise funds from Angel investors. How many they sold, I don’t know, but I bet its to genuine, bona-fide audio and music connoisseurs to whom bling is a dirty word and likely not even in their vocabulary. Old school audiophile comes to mind. I’m willing to wager that if Jonathan Weiss of Oswald Mills Audio where to ever venture down the path of digital, Echo’s End or something similar is very likely what he would conceive. It fits the bill. It’s all about the music, nothing more, nothing less. Here, Echo’s End shines and then some. Given that my music is generally of the 33-1/3 or 45 variety, my digital fix is served well with Roon. On the occasion that I spin a CD, there’s the EINSTEIN and Playback Designs that will do the trick. Have computer, will end all echoes. That’s it: Echo’s End is a DAC for a minimalist musicphile seeking to enhance his digital bits – nothing wrong with that.

    This "review" was painful to read. Too much fluff and half of the review was about the other equipment used. This is a dac. It converts digital to analog. No need to know what brand nas and laptop you use. The fact that the author was waxing poetic about all odbthe file formats the dac was able to handle leads me to believe technology might not be his strong suit. Next time it would be good to see some charts, graphs, etc. 

     

    Reviews like this are proof that some of these things should be conducted like wine tastings. You don't see the label, you don't know the brand. You only review based on what's in the glass.   Same here, I have a feeling this review was heavily Influenced by looks and marketing materials

    Kaiser acoustics currently use the twin enclosure Echo's End Reference Supreme edition, having compared it to other cost-no-object DACs costing $100k. Ours is about one third that price. 

     

    Do Kaiser make demos with it at HIGH END Munich in May?

    Thanks

    Hi Danny,

    Yeah, well that's the thing isn't it? Many companies are pricing their devices way beyond what I suspect 99% of audiophiles are likely willing to pay. If one places "sound quality" as the #1 priority, it is I believe realistic to say that there is no need to own a beautiful sounding DAC anywhere approaching that 20k price figure.

     

    Those kinds of prices are chasing the luxury market. The company knows they will sell very few; and they only need to sell a few to make a profit. What I've for years called "non-utilitarian" features of the device like how it looks, the exotic materials they're made of, or pride of ownership of something "special". I have no problem if anyone buys a device with those goals in mind.

     

    I know companies want to link the two: high-priced device made of unique construction/material = "better sound quality" and will create all kinds of "attribution theories" to explain why their device is special (such as the wood material having better vibration control). That linkage of ideas of course is not necessarily true. While I would love the look and feel of Panzerholz, there is as others have noted no reason to think this is any better than thick metal shielding for a DAC.

     

    Yeah... Lots of companies with lots of high priced goods. Nice to have options. But "good sound quality" I think is best correlated to the physical characteristics of the sound waves in our rooms and the quality of the electrical signals. For me, that's where "job #1" lies when it comes to writing a review and impressing upon the the readers that the gear is worthy/valuable for their consideration...

     

    completely in agreement with you - I have seen my fair share of fancy and extremely expensive casework make its way through Chez K only to be largely disappointed with the overall sound quality. Therein lies one of the problems with high-end audio... not that there aren't any other problems with it.......... 🤣

    Serious question regarding the casing: Would it influence the audio signal a wood enclosure versus an aluminum/metal enclosure? ...Say in an audio rack in proximity of other audio components and in the vicinity of audio interconnects, AC power cords and outlets, etc. ...Even a display nearby, or a laptop.

    Possible, sure.  Metal shielding is a bit of an art form, small changes can make big differences, but you are always reflecting or dissipating energy.  Dielectrics (insulators like wood/teflon/PVC) will always absorb/slow down airborne wave forms, but not reflect much energy if at all.  Whether these effects are audible to most people is open to debate. 

     

    In an ideal world,  an all dielectric solution MAY work better, but there are things to consider there.  Dielectrics work best when there are air gaps between signal/power wires, and the dielectric material itself contains a fair % of air in it's composition.  Kind of like foam.  When you foam an insulator like that, it gains volume/thickness quickly.  So you may gain performance but at the cost of added bulk, not to mention this route is more expensive to design. 

     

    I would imagine that a MDF entertainment center should do an OK job of keeping interference between components minimized, as it is quite thick and contains a good % of air.  The enclosure for this DAC is probably most of the cost, just due to material selection.  And like I stated earlier, subject to debate as to how much of an effect there actually is.

    I'm a little tired of people claiming that with 0.01% resistor it can't be more than a 13-14 bit DAC, while the measurements of my dam1021 module show a dynamic range of at least 130 dB....

    Dynamic range is not the same thing as linearity.

    You need the linearity to get the dynamic range. And the key here is level linearity, which is where the sign magnitude DAC really shines....

    Agree Chris. Listeners listen to what they like, they like their system regardless of what some might want them to think.  It ain't about them that's for sure.  Like you said, who cares, only the ones that want you to be just like them. 😉

     

    The point is, what are you after? If one enjoys the slant that a particular rig applies to everything it plays that's perfectly OK - but some then confuse that with the concept that "it's better at playback than other systems!".

     

    My own interest is in hearing what's on the recording, less additives - the rig is merely a means to an end.

    Most assuredly, Bob. Every time I do an major run at tweaking it turns out "everything matters"; one would be swamped by the number of things that one can experiment with, so I tend to focus on a different batch of areas with each effort.

     

    I end up pushing a particular combo of gear into what I consider an acceptable level of performance - I could always go much further, but there are only so many hours in the day ... :D.

    Crossover distortion is just one of many problems with a ladder DAC. At full scale, the distortion of a discrete resistor ladder is at best equivalent to 14 bits or thereabouts.

    I got my first round of "blow me over with a feather" SQ with a CDP that used a single PCM56, not even the premium version, per channel. This old warhorse chip has pretty miserable specs by today's standards - but that didn't get in the way of the system projecting massive soundstages, etc.

    I thought the latest ESS Sabre DAC was the best. 

     

    Anyway, it's the sound that counts, coming out from the measurements and the measured loudspeakers...the entire connection. ...The synergy of the implementation of all parts...big and small...everything's important, even our bank accounts, and cable transfers.

    That’s absolutely correct - duckduckgo-ing the interwebs, you’ll find that pointed out in other reviews. Then again, I wasn’t reviewing the Soekris DAC DIY module. My question is simply this: so what? I can buy Sabre and TI chips all day long and won’t be able to make a box sound anywhere near as good as proper digital gurus using the same parts. This DAC’s magic lies in the overall execution leveraging pre-fabed modules. Nothing wrong with that. If LL want to charge ten times the asking price for the finished product, let them. The market will decide if it’s saleable or not. 

     

    😎

     

     

    That's like reviewing a server and failing to mention it has a xeon processor with an intel motherboard.  Do the components of this device not matter at all?  Or was this review supposed to just be about the box and user experience without delving into any technical data.  Also, why are you using pics from the manufacturer?  I would think a review would include photos of what it really looks like.

    Will Kaiser demo with Lessloss in Munich?

     

    Usually in Munich we partner with Audionote Kondo Japan - which is deeply into analogue vinyl playback.

     

    We will have two systems with turntables and maybe a DAC. Kondo is not in favour of having a DAC.

    And when we have a DAC on the small system it should be one which is very well known. Sadly the Echo End Ref 2 chassis dac is not so well known as the MSB Ref DAC for example.

    So we will have most probably the MSB REF dac with femto options and 2 external power supplies,

     

    Privately in my showroom I listen to Lessloss  :). If you want to listen to this extraordinary machine and compare to vinyl or other DACs you can do that in the Kaiser showroom.

     

    Best regards

    Interesting that the first link that comes up when you google panzerholz is the LessLoss website.

    Just because  you have never heard of it, doesn't mean it hasn't been around. I have it on some machines in my shop including one that dates back to the 80's. A decade ago I looked into it for a project. IIRC, there was only one US dealer and a 10 sheet minimum.

    Oh i've heard of it before, like you said it's been around forever and I know it as tank wood.  Considering it is so widely used especially in speaker cabinets, it is strange to me that the first web link returned on google search is LessLoss a pretty small company.  

     

    They aren't using it in the typical manner.  I would expect the first returned link to be something like a wiki page or distributor, not a company pushing cabling/dacs.  Odd.

    The design requirements here, for a consumer in home audio device, are way different than the scenarios you are describing.  All the high precision applications you quoted main concern above all is durability.  Another problem is regulatory issues often requiring metal or nothing.  Of course metal wins out there.    Panzerholz cost more as well, why spend more when it will just fall apart in a humid/harsh environment, gets wet in a hospital, etc.  It is extremely dense so it should dissipate RF energy well as long as it doesn't get wet or beat on.

    Not a chance.  And if it did influence it, it would be in a negative way.  Think about all of the high precision laboratory equipment, medical devices, quantum computers, space shuttle electronics, etc. that are not encapsulated in a wooden box.   Its fine if someone wants to make a product like this and jack up the price;  I get it, there is a level of craftsmanship here.  But to say the wooden box is there because of performance reasons is absurd.

     

    Panzerholz (Tankwood) is used as the base of the core chassis of F1 cars. Here's a picture of one turned over:

    We did not choose this material for eye candy. We chose it for its performance. 

     

    We carried out a calibrated studio comparison of Panzerholz and aluminum and published the results here:

    On that page you can find audio examples which you can download yourself and run your own comparison. The difference is enormous. 

     

    Any current running through any conductor will create some amount of molecular movement. Current is defined as the flow of charged particles. If it did not have any friction it would also not generate any vibration. We are talking not only about miniscule amounts; surely everybody has heard a transformer buzz with their ears directly. Just how that buzz is dealt with through the design of the enclosure will also influence the final results of the audio performance.

     

    Here is another set of comparisons, with audio and video examples:

    If the build of an enclosure had no effect whatsoever on the resulting sound, nobody would be found tweaking these things. 

     

    Returning to the F1 application, you can find more Panzerholz inside the cars surrounding the car's timing electronics. Here is a sliced open F1 car. At around 3:30 you can clearly see the Panzerholz encapsulated onboard electronics:
