... surprise, now that the NE5532 are gone and the old filter set too that came with the Rotel (adapted to filter an oversampled signal), it is actually much softer. I can't say if it's "digital harshness gone" or if I should call it "muffled". Overall detail does not seem to have increased, but the detail that's there is more "balanced", meaning that now with just 20 Ohm resistors for i/v conversion and fed directly to the amp stage, some details stand out less than they did before. Bass has become tighter and much more prominent too. Odd, I would have thought the contrary.

The setup is now experimental and very unsophisticated: Iout to RCA via interconnect coax, shield carries Agnd, then to a resistor outside the box for easy access to fiddling. That means that before the i/v conversion there is already some 100's of pF cable capacitance that may act as a low pass. The resistors are garden variety carbon (gasp, I know, but I figured they're least likely to be inductive and they only convert the signal from i to v, they're not in the signal path proper). Plus my "pre" (haha) is a Rotel integrated amp that feeds my active speakers via the headphone out. That being said it's the same setup as before so differences are differences...

hope I'm not boring anyone with my little accounts of happy fiddling...
