UpTone EtherRegen measured. It's a switch.

[plissken]

Amir was able to get a unit to bench and the testing looks conclusive that it's not capable of doing anything more than a typical $60 switch.

The streamer he used has enough buffer to allow the swapping out of cables without breaking playback.

 

Here is one measurement up to 90Khz and showing no deviation vs a TP-Link switch. This is noise test so no tone is playing. Just looking at the Streamer noise floor.

That is incorrect. It also functions as a space heater.

Others can chime in about the operating temps to see if it's normal.

How does these measurements compare to UpTone's own measurements?

 

They don't have any.

What's even scarier is all the people that are patently hearing stuff that isn't there.

No, you have put forth guesses and conjecture.

 

Amir's data show no differences. Where's your data Alex?

I have no interest in being bullied, defamed, or threatened (they are having a field day of it over in the ASR thread)--and in our own sponsored forum I don't have to put up with it.

 

You aren't being bullied or defamed. You are however being exposed.

 

There is $10,000 out there waiting and again I'll cover the $1000 you would have to put up.

 

It's like at Whats Best Forum when I asked if you would sit for a blind evaluation on your ISO Regen and you said ANY DAY OF THE WEEK and then ghosted yourself for 18 months when someone took you up at your word.

 

Well what ever your word is worth now days.

 

You've managed to produce a switch that couldn't even get 802.11az correct out of the gate.

I find it very strange that skeptics talk themselves into not hearing things which are so very easy to hear.

We sell with a 30-day money-back guarantee, we don't advertise, and yet almost nobody ever returns our products (less than 1%), and they keep buying more. About 48% of our business is from return clients, and most all we get is praise.  So if your ears are clogged, don't blame me. 

 

 

I find it even stranger that I've offered to cover your $1000 side of a bet so you can walk away with $9000.

 

So if your ears are so clogged you can't bag an easy $9K....

Oh good grief, here you go again with that.  I do blind tests all the time. What I said in that one post was not an invitation. I'd sooner hack off my own toe than to invite Amir or you into my home.

 

Lol. I said we could do that at Axpona. Your product is a sham.

 

 

[plissken]

The measurement data is pretty damning.

Is this any industry standard test or was any testing done that conforms to a recognized method of testing switches?

 

 

 

The claim is one of audibility. Why wouldn't you test for audibility?

UpTone claims the EtherRegen can change the outputs of a DAC. Show me the affected output.

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.

Correct, all his tests aren't flawed or rigged, but must be taken with grains of salt and evaluated thoroughly.

 

Or if you have the chops and equipment: Debunk them.

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?

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.

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.

OMG, I guess I need to look at this. He tested a DAC without Ethernet input, to test the effects, if any, of an Ethernet "regen?" Please tell me how this makes any sense. 

 

Here is the product page for the EtherRegen. You show us where it's only intended purpose is for a Streamer and not a head end computer feeding a DAC over USB.

 

Here is what I'm refering to:

"  Across the ADIM™, at the other end of the EtherREGEN, is a single 100Mbps copper Ethernet port. This is the ‘B’-side port. Attach the computer/streamer/renderer endpoint that is directly connected to your DAC*to the ‘B’-side Ethernet port with a copper Ethernet cable. "

 

That's how i made sense of it. But then again that's just me.

 

Lets take your OMG one step further: You have a class of device in mind. Which one would you like tested?  How about something like a $100 or $200 Roku. You know something that most likely has the cheapest, bean counter, ethernet implementation known to mankind.

If Amir is telling his readers the ER does nothing, it seems to me, without doing the controlled listening test with independent, unbiased listeners, then his conclusion should, at a minimum, be taken with a grain of salt.

Wow. I wrongly assumed that the testing methodology used an Ethernet cable from the ER straight to a DAC's Ethernet input. Placing a computer in between the ER and the DAC seems to me to be crazy, if one wants to isolate variables. I would never make a conclusion based on this information. 

 

it's UpTones own marketing speak Chris! How can you be so obtuse?!

I hadn't read that bolded information about the ER. Interesting. However, don't you think someone running a test of a device would want to eliminate as many variable as possible.

 

Sauce that is good on goose is equally good on gander.

 

Thanks for the admission that you have been making talking points without any real research of what I and some others are actually talking about.

 

You can't back-peddle that a computer is a variable to eliminate when it's one of the variables the ER is supposed to correct for. It's a variable to test, not to eliminate.

No back peddling here. There's company marketing speak and there's reality. This is the nature of life since the first "lady of the night" advertised herself. The oldest profession is marketing. 

 

This is the exact situation I was talking about earlier. There are ways to run a test, to achieve a result that may not be the same if run another way. Engineers know how to test things under ideal conditions and less than ideal conditions. I real test would have taken into account some variables and actually tried to produce a result other than the one that was wished for. 

 

This thing smells even worse the more I know about it. 

 

Your options are to either poke holes in the testing, come up with your own testing that can be replicated, or using the information Amir has posted repeat the test and either come up with different outcomes or show repeatability.

 

HOW does this smell even worse as time goes on? What specifically about how he tested is problematic?

 

He tested direct to a Streamer, he tested to a computer driving a DAC. All per UpTone marketing speech.

 

You never did answer my question: How about he tests a Roku with the worlds cheapest possible Ethernet implementation. How about a $55 Raspberry  Pi 4?

 

What type, cost, class, economy of product will have a sufficiently poor Ethernet port that an audiophile switch is going to show a measured result on on the output of a DAC?

and the fact that this test used the most convoluted signal path imaginable

 

 

He went from Switch to Streamer. How's that convoluted?

 

I don't know about everyone here but my home network needs cannot be a router to a 5 port switch.

In the UpTone sponsored forum you can find them stating that having a general purpose computer between ER and DAC is not an optimal configuration.

So the online forum is to trump their product page?

 

One you have to sift through pages and pages and one it's right there. Jud that's a stretch.
