I like all kinds of audio stuff. Home Theater, car audio, pro audio...
Pic of my HT setup:
The entertainment center is made of the front speakers
6ft tall DIY line arrays with 16x 4" drivers and 21x silk dome tweeters per side, biamped with a DIY Tripath amplifier at about 50W per channel (~100W per side which is PLENTY!). Then center/rears are Atlantic Technology , a 15" Definitive sub, Onkyo TXSR708 receiver, TiVo HD, Xbox360, PS3 (not shown), and a Samsung 46" LCD 650 series.
Some misc. nice speakers in the car. I particularly like my old school USAmps USA400 amp... back when they made underrated high quality stuff.
In the PA department, have some old horn loaded EV 15" mains, two 18" primary subs (misc cabs with a PAS HL2880C and a Peavy Lowrider 18) and two 15" Cerwin Vega subs for added low end. 300WPC to mains, 900WPC to primary subs, 500WPC to secondary subs. Behringer DCX2496 processor to mesh it all together (works wonders!). Simple DJ-style mixer. All usually ran off of my laptop. Needless to say, it rocks the house.
