I'm looking for an excellent 5.1 system for my new Sony ES2000 (120Wx7) receiver. My budget is about $1000. My room is 12'x12'x10'. Seems to me that the three best contenders are... Ascend System 22-12 ($1030) Aperion Intimus 422/S-8 ($800) Mordaunt-Short Avant Premiere ($900?) Any thoughts, experiences, praises, or complaints with these systems is much appreciated! :)
