I have an HT system in my living room consisting of:
Receiver/amplifiers: Yamaha RX-V1400, with 2 Adcom GFA 535 II amps purchased used for $50 bucks each
Speakers: 4 Paradigm Studio 20's (surrounds) Studio CC center, Studio 40's (mains) v.2, a PW-2200 sub, and a mediocre Panasonic DVD player.

Downstairs in my studio are some custom built floorstanders in a tweeter-mid-woofer design using Vifa drivers assembled by a local speaker builder friend of mine. Much nicer sounding than my Studio 40's, but if you aren't looking at the front black baffle straight on, the raw MDF finish is quite ugly...the plan was to buy some grey carpet to match all my music gear...
These are powered by Rotel RB-1080 (floor demo) and an older Rotel Ra-971 I bought at a pawn shop for $100 bucks a while back.
Oh, and mediocre Yamaha CD player that does the trick.

I also some older H/K, Pioneer, and Marantz integrateds/receivers/av receivers in boxes in my garage with some older Wharfedale speakers that survive cold winters.
