Because the Ethernet interfaces built into most current DACs (for those that even offer them) are often poor performers. I am very particular about DACs, and I would never choose a DAC based on whether or not it had an ethernet interface. It is now rather trivial for any manufacturer to have a good USB inout in a DAC, this is not so with an ethernet interface which is much more difficult to develop and implement, and requires much more attention to do it right. And putting WiFi in any audio component is a very good way to seriously degrade audio performance. I do believe, that ultimately, there will be very good DACs, with very good Ethernet interfaces built in, we are just not there yet, although the Linn Klimax DS is one DAC with Ethernet which is very, very good (but still somewhat limited in sample rate).

Whats holding audiophile audio back... maybe focusing on cables, fuses etc. What is the actual question? Right now most DAC manufacturers do not have the capability (or time/money?) to develop their own Ethernet interface for inside the DAC, so they turn to pre made available solutions-unfortunately the solution most often used is made to a price point which does not allow for best performance. I think we have all seen specs for DAC's with ethernet inputs which only handle up to 24/192 and DSD 2, right? While we know that Ethernet is capable of much higher rates (Sonore Renderers handle at least 768 PCM and DSD 512, and likely higher, without any issues). Also, these affordable "solutions" are just not developed for best performance, they are developed for affordability. Certainly, the tech to put a really good Ethernet interface inside a DAC exists, as you are well aware; but right now that is not done (for the most part). As I said, as Ethernet distributed audio takes over from other methods, we will see more and more DACs with better Ethernet interfaces. In the mean time, external Ethernet renderers offer higher performance than what is currently available in most DACs.

What would you suggest I look at to become more familiar with this if anything? Thanks! I think we are a little off topic here, perhaps... Maybe the OP will indulge us a bit... What kind of "evidence" would you suggest? I am NOT going to mention specific products and throw them under the bus. But for a simple example, anyone can see the DACs which have Ethernet interfaces which only accept up to 24/192 and DSD 128, for just a simple example of limitations. But, that is not all I am talking about, I am a aware of many people who have DACs which have built in Ethernet interfaces, who instead choose to use a Sonore Renderer (and the USB input on their DAC), I suspect the same is true for other Renderers, but my own experience is with Sonore and its customers, for sound quality reasons. The fact is an Ethernet input is essentially a small computer, rendering Ethernet streams to a digital audio format requires a computer (albeit not a hugely powerful one). As mentioned, the one DAC I am aware of that does this pretty well is the Linn Klimax DS (although sample rate limited). Take a look at what is inside DACs in terms of ethernet interfaces and ask these questions: 1. Is the Ethernet interface powered by a completely separate power supply from the rest of the DAC? 2. Is the Ethernet interface's output fully galvanically isolated from the rest of the DAC? 3. Does the Ethernet interface offer optical input? 4. How good is the clock running the Ethernet interface? 5. Does the Ethernet interface support all sample rates to 768 PCM and DSD 512 (or even higher)? 6. Is the Ethernet interface well shielded physically from the rest of the DAC circuitry? 7. What software is the Ethernet interface running and is compatible with things like HQPlayer? The above are just the tip of the icebaerg, and the obvious things which I am aware of. I am sure that John Swenson could point out many, many more (highly technical) design details which matter to the sonic performance of a really good Ethernet interface. As what we have with an Ethernet Renderer is a small computer, if one is going to put that inside a DAC, one has to be very careful to isolate the noise produced by that computer from the DAC circuitry-computer processors are by their nature sources of noise. Doing this right, inside a DAC is not simply done, or very affordable, that is why the best stand alone Renderers cost significant money. Again I am not saying it is impossible, just a bit difficult and expensive, and I do believe in the future we will see more DACs with well implemented high performance (sound quality) Ethernet interfaces.

Barrows himself has said this "Even with a DAC with a well a galvanically isolated USB interface the difference was not subtle." Even with Ethernet, Uptone Audio has felt the need to develop an EtherRegen, so clearly there is more research needed in this whole area. Perhaps, but I view the situation a little differently: There is nothing "wrong" with most USB interfaces these days in quality DACs. The problem lies in the source. Anyone expecting to get good audio performance by connecting a consumer grade computer directly to (virtually) any DAC via USB is bound to be disappointed. What a surprise, the quality of the source matters! Well of course it does (at least in terms of noise), why would one expect it to be different. A consumer computer is not designed to be a high quality audio source, so of course it will benefit from some cleaning up. And what, cables matter, of course they do, again expecting it to be any different in the context of a high end audio system makes no sense. But none of those things are because of "problems" with USB. Every interface has its strengths and weaknesses, and none of them are "perfect", they all require really good implementation, including all the standard high end approaches, to achieve the best possible performance (clean power supplies, careful design implementation to reduce noise, specially engineered cables, etc). There is never a "magic bullet" which both is simple and easy to implement, cheap, AND offers the best sound quality. OK, so optical Ethernet is close to a magic bullet, but again, only when it is done really well! Remember, we are talking high end sound here, where the last 1% of performance matters; when that is the case, all the details need to be addressed.

Popular Post barrows Posted October 14, 2019 Popular Post Share Posted October 14, 2019 Umm, it confuse me to no end why anyone who feels that: "All USB audio is equally poor, in my estimation", would even bother clicking on a thread regarding the relative performance of USB cables in an audio context? The only explanation I can think of is that a person such this just likes to hear themselves talk (type). Anyway, this thread is about different USB cables, and peoples' actual observations about them, why not we keep it there. I would suggest that folks who have no experience testing various USB cables, actually have nothing to offer here. To get back on track, here are some of my observations: Lush (not Lush 2): For me this was a bit rounded off on transients, and somewhat lacking in ultimate low level resolution (reverberation tails for example, could not be followed as far down in level as with some others). It does have a relatively richer presentation, which might work for some people/systems. Inakustik Referenz: The opposite of the Lush, highly detailed, with very fast precise transients, and very, very good low level detail retrieval. Definitely worth a listen for anyone looking to eek out the last iota of detail. Nordost Tyr 2: My current reference, very detailed, very low apparent noise floor, with no sense of over-etching. Balanced Source: Various Sonore Rendu models (which reduces the differences between USB cables) DACs: DIY, various Buffalo builds, all USB interfaces galvanically isolated (and I2S lines re-clocked) from the DAC (which also reduces the influence of the USB cable). I see Curious has a new model, The Evolved, I would love to hear some impressions of it if anyone has one yet. Although I tend to be suspicious of USB cables which appear to be hand made (as I doubt they actually can meet the spec).

Popular Post barrows Posted October 15, 2019 Popular Post Share Posted October 15, 2019 @marce, I expect that kind of snarky comment from @mansr, but not you. Of course DC is DC, but one of the issues with the USB output of, say, an ordinary consumer computer is that the USB power lines actually do have an AC (noise) component on them (noise, in other words). This noise is easily measurable (easy enough so as not to need a spectrum analyzer to see it). This is one of the reasons Audiophiles can get better performance by using a component with a purposely (for audio) deigned USB output which reduces the noise on the 0 VDC and 5+VDC lines. Anyway, no one here has tried a Curious Evolved cable yet? I am curious myself...

barrows Posted October 17, 2019 Share Posted October 17, 2019 I use Sonore Renderers which have very, very clean USB outputs (measured), the entire thing is running only on ultra low noise linear supplies, including a dedicated LT 3045 for the USB bus power, and most of my regular DACs also have full galvanic isolation on their USB inputs. Still, the USB cable used matters, now that cable does not make as big a difference as it does if I try a standard MacBook Pro as a source for testing, but it does still matter. What do you know, I am not really surprised that in the context of a high end audio system the USB cable matters, hell, video folks see differences in video from different HDMI cables... John Swenson has repeatedly (why I will not ping him here, he does not need to waste his time on this anymore) explained how/why USB signal integrity matters, and HiFi News has published eye diagrams of various USB cables which show significant variances in signal integrity. sandyk 1 SO/ROON/HQPe: DSD 512-Sonore opticalModuleDeluxe-Signature Rendu optical with Well Tempered Clock--DIY DSC-2 DAC with SC Pure Clock--DIY Purifi Amplifier-Focus Audio FS888 speakers-JL E 112 sub-Nordost Tyr USB, DIY EventHorizon AC cables, Iconoclast XLR & speaker cables, Synergistic Purple Fuses, Spacetime system clarifiers.

Popular Post barrows Posted October 18, 2019 Popular Post Share Posted October 18, 2019 @marce, Look it up and see for yourself. I am sure some (audiophile, and cheap Chinese) cables do not meet spec. But the spec is only for accurate data transmission. I am sure in 99.99% of cases there is accurate data transmission, and that data errors have absolutely nothing to do with hearting different performance from different USB cables. This has been discussed on this site over and over, and I am not going to bother to re-hash it all here again. If you would actually like to learn some theories as why this may be (and no, I am not aware of any proof of these theories yet: measurements) search for John Swenson's posts on the topic.. If you would actually like to make a positive contribution here, with your considerable knowledge of high speed data transmission, as to why and how the different cables actually do result in different sonic results, that would be appreciated. Otherwise, the constant badgering of people who already know that different cables do sound different contributes nothing, and is just more noise. charlesphoto, AnotherSpin, Albrecht and 3 others 2 1 3 SO/ROON/HQPe: DSD 512-Sonore opticalModuleDeluxe-Signature Rendu optical with Well Tempered Clock--DIY DSC-2 DAC with SC Pure Clock--DIY Purifi Amplifier-Focus Audio FS888 speakers-JL E 112 sub-Nordost Tyr USB, DIY EventHorizon AC cables, Iconoclast XLR & speaker cables, Synergistic Purple Fuses, Spacetime system clarifiers.

barrows Posted October 18, 2019 Share Posted October 18, 2019 1. I would suspect that the question is overly simplistic in nature: what is "fine" when looking at the eye? If there is "noise" on the USB lines, at what frequencies and levels would/could this be problematic? And, if that noise is problematic, could/would it be solved by those USB cables which separately shield the data lines from the power/ground lines? 2. My understanding of John Swenson's theories on USB issues also includes USB signal integrity itself as a potential problem for increasing noise in the USB receiver-that signal integrity may be a function of how well the USB hub chip is functioning (and they are not all equal...). this signal integrity can be a separate issue from noise on the USB lines (data and power). OK, off to the PO for product shipping now...

Popular Post barrows Posted October 21, 2019 Popular Post Share Posted October 21, 2019 Wow! Really, as mentioned so many times before: no one is claiming there is any problem with losing data! That does not change the fact that different USB cables sound different. If you do not believe so, that is your opinion, but trying to convince people of such who knows better than you is a lost cause, a waste of your time, and mine. I would your posts if they actually had anything to offer, but they do not. You just keep stating your opinion, which is wrong according to my own direct experience testing such. I have no time for wrong opinions, they are just more noise. The proposed theory is that different levels of signal integrity give rise to different noise results in the USB receiver circuitry, and this noise makes its way to the important sections of the DAC circuitry (perhaps clock ground plane, perhaps analog stage, etc) where they create distortions/artifacts in the analog output. this is just a theory at this point, as an explanation for what many people actually hear.

My point was, that the USB output of some products is many times cleaner than that of a standard computer, and some DACs have well implemented galvanic isolation of their USB receiver sections. When these two things are applied in the same system context, the differences between USB cables are less obvious, but still audible, sometimes. Certainly these differences are audible enough that I have spent considerable time auditing various USB cables. For example, if I use a standard computer (say a MacBook Pro) as the source in my system (keeping the rest of the context the same), the differences between USB cables are more acute than when I use the Sonore Signature Rendu SE. But certainly, a system with more resolute speakers, amp(s), etc will reveal more of the differences between USB cables.

Its bad design in my book if anything is susceptible to the noise to such an extent, it should be 130-140dB down. This is the weird thing for me. For example, I see measured differences in jitter spectrum, where the differences are often at -120 and lower. And I agree that these differences Should not be audible, at least in what we see in the jitter measurements. I have participated in listening tests of different levels of jitter, say when just replacing the master XO with one of lower phase noise, where the measured jitter level differences are at such levels that one would conclude they Should be inaudible, but the differences are clearly audible. I have a very hard time believing that the difference which is heard is anything occurring below -120dB, as that does not make sense. Nevertheless, the difference is clearly audible, and does not require a microscopic focus to perceive. And the tests were confirmed with no knowledge of which XO was which, and were repeatable (essentially "blind" although I hate that term). I do not know how to explain where one needs to look to find the what is really affecting the sonic differences, I do not believe in magical qualities of audio playback. In my system, on a quiet night at home, I can perceive test tones at -100 and maybe -110, but not lower than that. So how can something at -120 or lower be affecting what I do hear? Is it possible for an artifact of jitter at -120 to be producing an IM product at an audible level? There is something there, but I admit to being not able to technically know what it is. sandyk and RickyV 2 SO/ROON/HQPe: DSD 512-Sonore opticalModuleDeluxe-Signature Rendu optical with Well Tempered Clock--DIY DSC-2 DAC with SC Pure Clock--DIY Purifi Amplifier-Focus Audio FS888 speakers-JL E 112 sub-Nordost Tyr USB, DIY EventHorizon AC cables, Iconoclast XLR & speaker cables, Synergistic Purple Fuses, Spacetime system clarifiers.

This is my point, @John Dyson's comment makes it sound like he believes DAC (and perhaps USB source) manufacturers are inept because the USB cable matters. I do not agree (at least not that all manufacturers are, there are some DACs with very well implemented USB receiver sections). In my view, it is not OK/fair for a lay person with no knowledge of such to call out manufacturers just because that lay person's personal view is that the USB cable should not matter, as they do not know what they are talking about. .
