EtherREGEN on the way!

Did Amirm test for ground leaks /loops. Did he test for smps noise, in all ways it may manifest itself. Wilcono is right when he said Amirm did "some" test. But did he do all test.

I sometimes find a change as simple as a switch may not jump out as different. Yet I may notice in a couple days I'm playing familiar tracks at a click or 2 higher on my preamp. Each click is 1 db on my preamp, Maybe I notice a sense of fatigue has left. Or, as I start comparing different sources they sound more and more similar. Blind test is one thing. Songs grabbing your attention, making you sit up and listen with rapture is another form of validation changes are moving in the correct direction .

I've followed all the talk about the EtherRegen both at AS (Audiophile Style) and ASR ( Armin's Audio Science Review). Despite some of the reactions at ASR being hostile and juvenile, I think they raise important issues about the state of AudioNervosastan.

....

The user reports at AS are bordering on ecstatic.

Not all the user reports were ecstatic. Some were and some were similar to "there was an improvement/I like it."

When you did your testing did you remove the other switches and Gigafoil? I am asking since those devices could be doing some of the same things that the EtherREGEN is supposed to be doing. Thus, for you, the eR could be redundant.

I bought an eR and it replaced a standard switch. I felt that the noise floor was lowered. It wasn't night and day but I plan on keeping it. I also have a very simple setup (server PC to eR to Sonore endpoint).

Armin can't test for the passage of high-impedance leakage currents between different Ethernet switches because he doesn't have the test equipment. AFAIK, only John Swenson has the test equipment to measure this that has an audible impact on clock phase noise.

Check back with us once you have 150-200 hours on it.

My ER has resulted in a notable and audible reduction in the noise floor and overall improvement in the sound quality of my digital streaming front end, and I am using a Gigafoil-comparable device for optical isolation, the Sonore Optical Module, at the front end of the chain where the server and router reside in the bedroom/study.

As soon as I installed the ER, I could hear things in my system I had simply not heard before, e.g. secondary sound reflections off the opposite wall in the recording studio. As my ER has gotten over 200 hours on it now, there is a notable improvement in the detail, transparency, naturalness of instruments and vocals, and a concomitant improvement in hall or recording venue ambience cues, spatiality, imaging precision, depth and width and instrumental detail, texture and tone color.

To sum up, my system has never sounded better and has become very, very compelling and engaging to listen to.

That's a good point. I should have mentioned that. So they may indeed be redundant to each other.

I primarily tested: Cisco switch > ethernet > gigafoil > server
to ---------------------------------- -------------eRegen ----------------

Willco, Uptone recommends the EtherREGEN be the last device before connecting to your network Bridge, streamer or Ethernet-capable DAC. I think that's your configuration, but I'm not sure from your schematic above.

I have well over 200 hours. Again, I really like it and it has improved my sound. It is also hard to do exact comparisons with and without since other things have changed. Maybe one day I will pull it to really see what it is doing.

I thought someone else in the Uptone Audio thread also had a gigafoil and said that the eR made a much bigger difference when it wasn't in the chain.
 
Doesn’t Uptone provide 30 days return policy? If so, it’s relatively risk free to try, isn’t it.

I’m hoping I can use this not only for the DAC but for my appletv as well. Gigafoil only has one output which goes to my DAC. I will try with & without Gigafoil and before & after Gigafoil as well when it arrives in January.
 
Bottom line, the difference has to be audible.

I use the same reference tracks over and over and comfortable with my ability to determine what I hear.

I will admit, sometimes at first listening I have fooled myself not following my rule of different or better and it does not come out until a day or so later.

This just recently happened unrelated to a switch and I reverted back to original configuration - with all this being said, there is also a time to leave well enough alone, and I can’t believe I just said that [emoji2957]

As fate might have it, my gigafoil stopped working the day I planned to ship the eR off to the Netherlands. So, I decided to hook the eR in again and this time run fiber out of it's sfp port. I had noticed an improvement in clarity when I tested fiber out of the eR before and had planned to run fiber out of the Cisco switch, but their proprietary sfp modules are expensive...

So anyway, everything sounds great as is. I'm not going to spend any more time trying to figure what's what as I also just added an Uberbuss (to replace a ps audio p12 regenerator) so that's having a positive influence as well.

I’m sorry to hear that G/F failed.

Do you think it was some type of surge?

I desire to thank everyone who participated in this set of posts. It just greatly influenced my next purchase. Many thanks.

I don't use a Gigafoil (I had a Gisa isolator, but did not put it back in). Pretty much my impression of improvements as well. The only other isolation device is on the first ethernet out of the cable modem. I did a secondary change a couple weeks after getting the etherRegen in my system. I changed to optical from switch to etherRegen. I did not notice a difference with that system change.
 
I own both AQvox SE And etherREGEN switch. Sadly to say: etherREGEN does not improve anything. It just run very hot. That’s it.
 
Aqvox SE did improve the SQ comparing to the normal switch but not at the level of Ansuz powerswitch D2 which i had chance to try in my system.
 
The Ether Regen will also improve the sound over a Best Buy switch. It comes down to budget and how far do you want to take it.
I never liked the idea of stacking in series any component. There are cases where it works. My personal belief is buy the "one" that best suits your situation and budget.

If you're open to sharing it, I'd welcome seeing a diagram or plan of how you're using the Ethernet switch in your system.

If you have had your ER for less than 30 days, you can return it for a full refund, no questions asked.

We just had Alex Crespi on as our guest speaker at out SFAS meeting this Saturday, and Alex mentioned that of over 1500 ERs sold to date, only 5 have been returned.

That is a satisfied customer proportion of 99.7% (to date; Alex is getting ready to ship out 250 more next week).
