Looking for a second system in the basement 15x30 feet and would like to run some old 4ohm Spica TC50s in a work room (second zone). Anyone make a recommendable 7.1 for $500 or so where I can run two of the channels in the second zone and a 5.1 HT for the kid's TV??? If not where would 'recommendable' start? (Ya like that open ended question leads us). I really can't go past about $750.
