I thought LME49720 were the originals for LPF, also the NE5532 from I/V look odd. However, swap the 6 opamps with 4 x NE5532 + 2 x 49720 bought from a credible source (Digikey, TME etc.)

Guess i will have have to try. Just out of curiousity i opened my first and perfectly functioning unit to check for differences and i noticed on the back that my functioning unit is marked XONAR_E/B/A and the faulty unit is marked XONAR_E/B

*edit* further investigation leads me to believe that my first unit (XONAR_E/B/A) is the plus version and the E/B is the non-plus stock version.

Just in case someone might be interest I have a A10 pot that I would be willing to send to anyone (preferably in the EU) with a non-Muse edition of this DAC. I previously had a non-Muse edition that had some imbalance because of the B10 pot.
I scavenged everything I could from my dead Muse edition before going for an E3. I am keeping the Muse01 amps but I have no use for the pot.
Changing it is not for the faint of heart though.
EDIT : Sent to someone
