Several huge hard drives (500GB costs about $100 these days), dedicated music network (Sonos recommended, as it creates its own "tunnel" and is not dependent on working PCs), DSPs. CD is not for playing, only for ripping to FLAC, Apple Lossless, WAVE or AIFF!
I have found that DVDA is not really worth it. Sounds a bit more dynamic, but the real drama is in the totally different mix. Often prefer the original. Pristine, untouched masters is difficult to get in hi-rez. 16/44.1 seem to be the gold standard. Unproblematic and user friendly.

Current M-related equipment: DSP7000 (2), G91A FM, Sonos ZP90/ZP80 Zone Players, F80 (kitchen,yellow).
