The change of the sound to a darker one happened when I changed the RCA interconnects from Chord C-Line to Chord Clearway. In the past, when I bought the ISO Regen, I had the feeling that is was damaging somehow the sound. Today I tried it again, the only difference being the Clearway, and the sound seems fuller and the bass more precise.
From the ISO Regen to Qutest I use the included USPCB adapter which can be found here:

You can see it also in the picture. It is the 90 degree turned version.
