i have a set of the logitech 5500. 5.1 500watt blah blah blah.... i read over a dozen reviews prior to purchasing this set for 230.. and its f'n horrible.. the sateliites suck.. teh center channels rated at like 160+ watts and its obviuosly teh weakest link of the bunch.. the sub is very monotone, and i still cannot get a true dolby logic 2 signal output from my spdif toslink cable in gt4... these speakers suck for music, they are just "ok" definetly not worth 200+ dollars and they are ashamed to bear the THX logo on them... i dunno what people have been smoking when they wrote their reviews... personally i only bought them w/o ever hearing them and i totaly regret it.. if i heard them first, this dilema would not be happening,, but i was stoopid enough to trust over 20+ different reviews on how outrageoulsy good this system is.. and they jsut plain suck.!!!!!
