Which would you pick between the two DAC.

Your overconfidence is noted and evident to all, audioman58. I am guessing that there are those here that cannot/choose not to afford your utopian DAC and even more that would prefer another.

Likely a very good recommendation but equally likely to be ignored due to your style. A shame, that.

Dave,

Thank you.  I will take a look at it.  I almost get ISO Regen while back when I first got Modi Multibit and had noise problem with USB signal with iMac.  What I did was I disconnected usb 5V from iMac and run 5V from the wall and no more noise.   

Thank you everyone for your input.  

Exogal Comet Plus is awesome. I believe they are the Wadia engineers from before the recent corporate takeover. 

Agree that the Comet Plus is a special and very good sounding DAC. A true bargain at street price or maybe at any price. Its resolution raises my bar yet brings the slightest imperfection/mismatch of accompanying cables, cords, fuses, etc into the forefront. Purist Audio's top products proved to be the answer in my system, room, ears.

The executives of Exogal and the Chief Engineer Jim Kinne were indeed the brains behind Wadia in its glory days.
