My SS drive Mac mini always sounded good but, adding the Mojo Audio filter, linear PS, outboard AV drive, and cables took the performance to a level beyond my $7K disc player, IMO. Does this still fall short of being "audiophile grade?"
depends on who you talk to. Adding Mojo trinkets (or any other modder du jour) is undoubtedly efficacious. You are still building a server around a non-audio device that is jittery and noisy, thus the creation of things like the Offramp. Only one way to find out what is missing.
The new one box Sony digital spinner has some promise as does the Auralic Aries and points to where things are going:
