I'm powering the VR2's with a NAD T763 integrated multi channel amp. My room is fairly large and the 100watts/channel is enough to fill it nicely. I've only had the VR2's for two weeks so I'm still playing with my options. I've got an Onyx Rocket UFW-10 sub that I can't seem to let go of, despite trying. I've finally dialed in the 2900 and figured out how to go 2 channel and 2.1, and 2.1 just adds so much. The VR2's are rated down to 25hz, just like the UFW-10, but the sub has just a touch more presence, without being sloppy, so I end up listening 2.1 most of the time. The thing that has impressed me the most is the rear firing tweeter. There are times when I swear that there is a crowd behind me, going crazy. Its weird, but makes for a really cool experience.
Basically, I'm stuck with multi-channel b/c I really enjoy watching movies in 5.1. However, my next home purchase will have to take into consideration a dedicated two channel room, but for now, I'm happy with what I've got!
Escott has the deal, though. The Cary has just enough juice to push the 4jr's. The results are jaw dropping. Superb imaging and soundstage...
