I just received two monoblocks on Tuesday and finally today have them setup to drive my front Boston Acoustics VR-M90s. I ordered a pair of Outlaw PCA 1.8m cables with these. I'm impressed with the quality of these cables and am very happy that I purchased them.
As for the sound of the monoblocks, it seems as if my M90s are finally getting the power that they like. I was driving these with a Yamaha RX-V2200, as well and a VR-MC center and a pair of VR-MXes with a Yamaha YST-SW800 powered subwoofer, and the M90s sounded a little sluggish. The sound that the M90s produced was good, but it seems to have gotten significantly better when I put these on the two m-blocks. I think that you'll be very happy with the m-blocks.
