Let's see, I mostly use CD's, so it usually starts with a Rega Apollo, then moves on to a Vincent SA-31 MK pre-amp. From there, one output goes to a NuTube headphone amp that I built and really dig. When the amp arrives (Adcom 6602) it will power up a set of Decware ZOB speakers (Zen Open Baffle). I am pretty picky about power, so I use a BPT isolation transformer that produces balanced power from six separate secondary windings. Power cords vary, but PS Audio Preludes, Pangea AC14 SE, and one from BPT as well. Speaker cable has been Maple Shade basic twisted cable, which I have always liked, and interconnects are Nordost Blue Heaven from the CD player, and one Audio Magic from the pre-amp to the headphone amp, and then Straight Wire from the TV to the Pre-amp as well. I occasionally use a dedicated a small laptop set up just for sound reproduction by a friend of mine, and it is amazing. That's about it.
