Apparently, bypassing the DSP1 also defeats oversampling, which is kind of a problem
However, I might have nailed down my issue with the Ref 7.1. Some high res material at 24/96 sounded absolutely stellar (talking only from a timing perspective), while regular CDRB format file simply did not. But if I am not mistaken, I realize that the master clock of the DSP1 only supports 32khz and 48khz (256Fs, 384Fs, 512Fs and 768Fs). So I decided to use Pure Music excellent SRC build in engine to upsample everything to 24/96. Improvements were obvious in my system when playing back native CDRB files. I am very curious to hear what other Ref 7.1 owners think about this.
I will also try to turn off the PLL (the AP2 might not need it) to see if it can get even better. But I need first to figure out how to open it

EDIT: does anyone have tried disabling completely the DSP1 ? It seems to me the AP2 does not really need jitter correction and I feel tempted to disable it. Would that still work without damaging anything ? I see there is also a NOS setting that may improve timing and flow but at the expense of separation and clarity.
