I'd be pairing the B4's (as the L/R Front speaker) with the Bronze Centre, since matching the front & center is always a good idea. Hehe.
As for receiver wise, do you know how Denon's avr-1905 compares with thw 2105? I think those two are the main ones i'm considering right now. With them being relatively new, it's a bit hard for me to find more information on them. So i'd appreciate any info you may have. Thanks!
