My current system:

JVC 56" RPTV
Dish HDTV Satellite system
Outlaw 950 Preamp (just sold a nice Marantz
550 that played great)
Rotel RB-985 5x100 Amp
Magnepan MG 12's up front
Magnepan MMG's in the rear
Magnepan MMG-C center
Panasonic CP-72 DVD player
Sony Tape Deck
Acoustic Research Subwoofer (to be replaced
as soon as Outlaw, Hsu, or SVS as a sale)
Not into the cost of high-end cables yet. Still looking for empirical research to suggest they really do make a difference.
