first off,and it sounds like you know,you gotta lose the bose.and the sony too.sony does make good stuff,but you must go right to the top of the line.i listen to heavy music(heavier than what you list)and i get by with b&w 601s with a monitor asw-210 sub,with impressive results.
and though you may get lucky,i believe a good music system will play back movies with good results,the opposite does not always hold true.if you can wait,then get on the 1070 list.i own a 1050 with ext. amps that i love for music and it does a damn good job of 5.1 (6.1 if i was motivated)
