Any opinions? I have Boston T1030 LR, and VR-23 C speakers. I currently have Infinity bookshelf rear speakers(monopolar). I plan on buying the Onkyo 989 (130W, 7.1 THX Ultra) receiver. I'd like to use the Infinity speakers as surround back and get new surround speakers. I'm trying to decide between the Boston VR-MX and the Boston VRS (100W max capability). My system will be used about 60% for home theater and 40% for music.
