With my system Diana Krall 24/96 sounds worst than CD and a LP ripped version and Jazz at Pawnshop 24/88.2 sounds much better that any CD version I have tried !!!
I'm using previous Mac Mini with separate power supply, Weiss INT 202, NBS Statement digital cable and dCS Elgar Plus with latest firmware version.
I was thinking upload my AIF converted Jazz at Pawnshop for another ones try and post their opinions!
I think the weak link in computer audio is USB, but I never tested a lot of options, I decided first by Weiss approach that I found the most consistent.
Thanks,
