@Azjake: The Accuphase gear does look very interesting, but super-expensive as well, especially for the two-box combo. I'll make it a priority to try it out, though.
@Guidocorona: I do have the K-01 in balanced mode. I'm not a fan of the DSD filter on CDs, though it does seem to sound different than the DSD filter on SACDs. The only thing I dislike about its performance on SACDs is a dry, recessed midrange that over-emphasizes the treble and bass. I'm a mids freak so this is a major con for me. Luckily, my SACD collection is small compared to my CD/FLAC collection. As for the Esoteric clock, I did audition and honestly couldn't tell any difference at all. I can't imagine why a clock would be at all useful for a single-box player. As for cabling, I use Virtual Dynamics, which are copper cables with a house sound that's very rich and full, so the lack of warmth/richness I'm hearing in the K-01 certainly isn't a cabling problem. I don't have any conditioning, but have my system running directly to two dedicated lines. I usually listen late at night so I've never thought power conditioning would help much on my system.
@Dob: For Vibration control I have a Monaco Modular Rack. Getting a wood-based stand might help, but I can't imagine it helping to the degree I'm talking about. As for a server, I had a custom PC built to the specifications that Goodwin's audio recommended (basically the PC is isolated and dead-quiet, built specifically as use as a server, accessing my music from an off-network Synology NAS).
