At the moment i'm running an Adcom GTP-400 preamp ($100), Onkyo M5150 poweramp ($75 ridiculous amounts of power. Modded to bench 347wpc @ 4ohms), Pioneer Elite DV-50A ($50, discontinued floor model locally), Paradigm Esprit V.3s ($150 off a forum), Klipsch RW-10D ($250 locally from a guy that works at Klipsch, brand new), and some good cables and interconnects. OH! And a Sansui TU-5500 tuner in perfect condition. (1978 vintage, $15 a flea market.)
The HT set is more Grassroots, but i'm not as proud of it. Just a 7.1 Onkyo reciever with a few pairs of decent speakers w/ dual Mirage Omni S8 subwoofers.
It's just as amazing the stuff you can find on Craigslist in terms of audio as what we find in cars. It's nifty.
I'll try to get pics up of my setup.
