I’ve been getting some of the funny behavior with the ISO REGEN detailed here: https://www.computeraudiophile.com/forums/topic/31877-iso-regen-listening-impressions-kicked-off-with-some-measurements/?do=findComment&comment=714912
It happens after hours of music playing, not minutes fortunately. The ISO REGEN (hub) loses connection and music stops. I’m guessing that’s the result of the static buildup and then the discharge.
Of course it may be other parts of my system causing this but the DAC/Pre isolation is mentioned in that post above so just wanted to double check the DS side of things with you.
I swapped out the Corning optical cable to rule that out, for a Supra certified cable both upstream and downstream of the ISO REGEN. But I still get the same result after some hours of music playing.
A generic Cheap-Charlie hub has no issues in this exact same chain, so I assume it’s this isolation chip of the ISO REGEN, as discussed in the post above. Also with the isolation switched OFF there are no issues. Which leads me to believe it’s the ISO part causing issues. I do understand the Regen has many more benefits than just the isolation but I’m trying to understand what interaction of the isolation between the Regen and the DS may be causing this.
The 24/192 Stereo Bit Perfect test passes with all combinations of cables above - the Uptone 90-ohm USPCB, the Corning optical and the Supra certified USB. But I’m sticking with the Supra certified cables on both sides of the Regen for all troubleshooting since that’s the only one with the USB logo on the box. And the Bit Perfect Test passes with both Regen isolation on and off. So I’m trying to work out why the isolation causes the hub to briefly lose connection and stop the music in the process.
So that’s the background info for the issues I’m having. The questions I had were:
Is there any kind of digital isolation of the DS USB input? If not, is there anything that comes to mind as to what may be causing this, at least from the DS USB input side of things.
If I followed Uptone’s recommendation of trying a wire from the ISO Regen output to a chassis grounded point of the DAC, then could I try wire under the screw which is above the Toslink input, as a chassis grounded point? Or is there a better screw to use for earthing?
Appreciate any advice
