UpTone EtherRegen measured. It's a switch.

It's very relevant because whenever numbers and measurements are involved, those with the knowledge are at an advantage over laymen. Laymen have no idea if there are games being played with this measurement or its results.

Hence the reason that 3rd party results are always required in the science world.  It's called peer review (round robin), however; when the manufacture can't produce what they is indeed the baseline, it's hard to "prove" the baseline since in this case there is NO scientific data to backup any claims.

For whatever it's worth, I don't seen any signs of gameplay here.

I'm not sure what facts I can reveal, but people can put some of the dots together by looking at the evidence that's public. If your company helps Amir make money your products won't be talked about in the same vein and won't have a subjective slime wrapped around the measurements. 

 

Seriously, start by asking him why he hasn't measured the Berkeley Audio Design current production products and compared them to his list of inexpensive products. He certainly has access to the products. He was and still may be a dealer for them. He is friends with Michael Ritter from way back in the Pacific Microsonics / Microsoft acquisition days. 

 

Ever wonder why he is a big supporter of MQA? The dots are there to be connected. They revolve around money and friendships. 

 

Why does this matter? Because it's the tip of the iceberg and oozes into everything done over there. 

 

Smells a little like the basement of the pizza parlor incident @Jud referred to earlier. Those involved also just "connected the dots". 

 

But as @mansr said, attacking an individual (even if it's well deserved) does not do anything to negate measurement results. All it does is demonstrate that those attacking have nothing better to counter real evidence. Chris, you asked for the "discussion based on information" and then share these conspiracy theories against Amir. Does that even make sense?

I gave you some facts that you ignored. Not even close to conspiracy theories. 

 

You seem to be in the THD+N crowd. All measurements exist in a vacuum and must be taken at face value. The world is black and white. This isn't a personal attack, just an observation that you can help backup or refute.

Let's try an analogy (and invoke Godwin's law):

1. The Nazis invented rockets.

2. The Nazis were evil.

3. Therefore, rockets do not work.

Conspiracy theory about me this time? :) I think it's important to stick to the facts, Chris, and not to make assumptions about individuals. This is where most of these threads get derailed, IMHO.

 

I'm in no crowd. In fact, I'm in the "prove it to me" crowd. Look at my signature and check out the Distort tool I started building recently. It's designed to answer exactly the question of what levels of THD, and THD+N are audible. Do you think I'd waste my time building tools like DeltaWave and Distort if I didn't want to see real proof, real evidence instead of these constant appeals to authority and to the opinion of the crowd that dominate the discussion here? (and to a significant degree on ASR, as well)

I have no basis to assume anything wrong with the measurements themselves - I don't have the technical knowledge to judge. I note @Miska's comment about digital silence, but I don't know whether the particular DACs used in the testing behave in the way he describes, or precisely how the measurements were done.

 

Beyond the measurements there's a fair amount of unconfirmed innuendo regarding EMI radiation of an item that is labeled as being within acceptable parameters in that regard, and how operating temperature might relate to expected life, something UpTone clarified in advance of sale (that the unit runs hot, that this is within design parameters, and it is not expecting to shorten the operating life of the ER). To me this is innuendo and out the other (🙂), but it looks intended to insinuate rather than inform. It doesn't make the measurements inaccurate, but it does seem clearly indicative of bias.

The fairest thing we can experience is the mysterious. It is the fundamental emotion which stands at the cradle of true art and true science. - Einstein

I agree 100%. 

 

While he is likely not attempting to conduct rigorous tests, his believers certainly use his results as definitive answers and ammunition with which to assassinate anyone who isn't in the cult.

Patently not true. What a lot of us are looking for is a manufacturer to say:

 

No these are the wrong tests. Here are the tests we used internally and here is how you replicate them.

OK, maybe that's a bit too harsh. However, the measurements at ASR are created to be used as weapons against those who Amir doesn't have business or personal relationships with. 

 

Again not true. The measurements are the measurements. If you've a problem then out measure him or prove is wrong, incomplete, inconclusive.

You will never see Amir measure  a current production Berkeley Audio Design product, compare it to a $100 DAC that measures equally as good, and excoriate Berkeley Audio Design. It won't happen. Those who admire his work should ask him why he is playing favorites, publishing results that only effect people that aren't in his inner circle. 

 

What's your point here Chris? He's measured scores of DAC's now, many of them a fraction of the price of a Berkeley product that he recommends.

 

You're painting a picture of conflict of interest where none exists.

OK excellent. Was the test methodology one rigorous enough or standard so it could determine audibility outside this specific test run on this specific hardware under these specific conditions?

It's both a start and better than anything I've seen from any vendor of any purported Audiophile Switch.

 

These are buffered systems that you can start play back on and pull the Network Cable out of and still continue play.

What if the DAC used for testing has similar technology to the EtherRegen making it immune to its claimed benefits? Does anyone know more about this?

 

That's why a Schiit Modi 2 was also tested. It's a DAC known for it's demonstrably flawed input and even that the needle didn't move on it when driven. Or is the computer used to drive the Modi 2 have similar technology to the EtherRegen?

The power supply (from a Chinese OEM) is certified and labeled. The main unit is neither.

Amir, Plissken and mansr all have a huge hate boner against Uptone Audio. It's just incredible, the time and effort they spend to attack this company.

 

The first two for sure. Absolutely! For some type of personal vendetta. As for Mansr, I would not pay much attention. Because, well.... he is The Troll. (that's how he named himself)

Nonsense. I have a great system that I enjoy listening to. I like to spend my money on products that have demonstrable benefits. I'm perfectly capable of buying the ER or any other add on product and "hearing" an SQ bump in sighted listening. I prefer not to spend my money just to engage in self deception. 

And don't misunderstand: if reputable measurements come out showing what the ER does, I'd be glad to buy it. I'd also probably buy it if several well run/designed blind listening tests showed it to make an audible difference. I am willing to entertain the possibility that there are aspects to audio we don't know how to measure. I'm just not willing to use that catch all explanation for every sighted (and by definition) biased listening test. 

 

well put

 

I would still like to know how all that noise gets past the transformers on wired Ethernet, so that this sort of thing is needed at all.  The other "explanations" for this item make no sense at all.  Without proof this product look like a dud.

The measured noise is of course (largely) created by the DAC. That is entirely expected. What the test shows is that the output of the DAC is not influenced by the choice of Ethernet switch. Even if the switches do something differently, the DAC doesn't care. So why pay 10x more for no change in outcome?

 

Do you give any credence to the argument that the measurements should have been made with music playing?

Sorry, but which part of the posted measurements is biased and presumptuous?

Biased and presumptuous the conclusions being made about what the measurements mean. 

 

Biased and presumptions that many (as far as I can tell) sane and discerning folks are fooling themselves by buying the ER.

Not at all.

 

As a matter of fact I created a thread here about the ISO Regen improving the Schiit Modi 2 output. Now on other competently designed DAC's the proper isolation and filtering was already there.

 

Also it was Amir that did that measurement.

Assuming arguendo that the above is true, how does it affect these measurements?

 

Did his bias cause him to misread the noise analyzer?

 

Did his bias lead him to mis-perform the measurements in some manner?

 

Did his bias affect the screenshots he posted?
