Alright, I make you guys wait for so many other things. It is a jig to hold a whole bunch of USPCB A>B Adapters by their 'A' plug so the printed (and hole punched for the VBUS DIP switch) heat shrink tubing can be placed and heated. No other way to do it. Aloha. In a few hours we leave to S.F. for the night, and fly to Oahu in the morning. Just a reminder to anyone thinking about driving over and picking up their ISO REGEN early while I'm gone: My assistant and her burly firefighter husband are house sitting, so our giant dog, the cats, and the horses don't get lonely.

kalinka Posted April 30, 2017 Share Posted April 30, 2017 Slightly off topic: as I stated before, I use the original Regen together with an ipurifier 2. It was regen -> purifier -> dac. However, I've decided to try the ipurifier before the regen, and my system sounds so much better like this. With the ipurifier after the regen I was getting some fatigue, the mids was a bit too foward and harsh. With the regen just before the DAC everything sounds better and smoother. So, my advice is, for those who, like me, use the regen together with other USB "decrapfiers", try to use the regen at the very end of the chain, at least in my system it made noticeable difference - for the better.

No surprise there. You always want the device which provides the best signal integrity as the last one--going into your DAC. That would be the REGEN. UpTone Audio LLC Link to comment

For which devices are we likely going to need to use it? Alex already pointed out that this also gives us the ability to evaluate how much GI contributes to the sound quality. It is not a "device" specific issue, it is a system configuration issue. There is no way to give a hard and fast "this exact configuration" will have an issue. The exact precise mechanisms are not known so there is no way to make precise proclamations about this. There is a higher probability there might be an issue when people have systems that have already had extensive isolation work done such as devices run off batteries, isolation transformers, optical interfaces etc. And in the situations where we have found this happening adding a ground to exactly one point in the system has alleviated the situation, so to be accurate there has been no known situation where the switch was actually required, although it does help a LOT in figuring out what is going on so the grounding can be applied. I am NOT going to name specific devices involved in the situations where we found this happening because it is NOT device specific, a configuration where this happened had the issue with many different pieces of equipment in the same configuration. The upshot is that in all the isolation going on in a system just make sure you have one and only one point of ground in the system and you should not have the problem. John S. Link to comment

Well to be honest, I can not personally vouch for the "one and only one" ground point admonition in relation to ISO REGEN use. In my system I had ZERO ground points with EVERYTHING floated from mains (I've just never found there to be anything on my house ground of benefit to an audio system; and yes I know and accept the potential hazard). So the problem I experienced was that I needed at least one component grounded--otherwise I needed to use the "ground isolation defeat switch" on the ISO REGEN. Of course most all of you know that it is best practice to either have just one component grounded to mains (I'd picked the power amp), or to have all your components plugged into the same low impedance power strip. Multiple mains ground points in an audio system just invites in ground loop hum and other issues. ---------- By the way, I don't do Facebook or post cat videos, and you guys are my online social circle, I'll bore you with snapshots of our delicious meal right on the beach tonight (my lovely wife made me crop her out of her scallops dish photo because I caught her chewing!)

kalinka Posted May 2, 2017 Share Posted May 2, 2017 I have a question for those who already listened to the iso regen: how much better you would say it is when compared to the original regen? Let's say, in a scale of 0 to 100%, how much better the iso regen is? I know this kind of question might be tricky to answer, but I'm not looking for some scientific answer - just something to keep the curiosity & anxiety under control, lol. Link to comment
