ISO REGEN Listening Impressions (kicked off with some measurements)

In my experience - and this is purely empirical:

1. you want the component with the "best" clock closest to the DAC. Which has the better clock - the iFi or the ISO-R? I'm not going to presume to know.
2. you want the isolating supply (LPS-1) after the galvanic isolation

However, realize that these are only starting points. Don't assume anything. Experiment both ways and decide with your ears. Then report back, because it helps build the collective wisdom.

 

 

It appears the ISO Regen uses this oscillator (Crystek CCHD-575) : http://www.crystek.com/crystal/spec-sheets/clock/CCHD-575.pdf

From the spec sheet : 

Frequency Range:12 MHz to 125 MHz*

Phase Jitter: (12kHz~80MHz) 82 fSec RMS Typical @ 100 MHz
