I bought two A07s, one to experiment with and one to listen to (and maybe eventually I will try bi-amping).
I own multiple preamps (Transcendent Grounded Grid, Hafler DH-101 x 2), Musical Fidelity preamp out from M1Clic, Musical Fideltiy preamp out from A1-2008, FIIO headphone out, etc, etc, etc.
Would there be any sonic advantage to bypassing the "preamp/input buffer stage/volume control" of the A07 and use my other preamps for line level gain and volume control, and the A07 just for power? Due to the A07 having only one input I am now always using external preamp so I juggle two volume controls.
If there would be a potential sonic improvement, what would be involved in a bypass effort?
Maybe just short the volume control?
