I have am using my 1050 as a Pre/Pro and Center/Rear Amp. My center channel speaker is a NHT VS1.4 which recommends 50 to 150 watts of power. My rear channels speakers are pretty much junk.
I was looking to upgrade the rears to NHT SB-1's or a pair of VS1.4's and possibly get the 200 for the center channel. I am running a Parasound 1200A (205 watts per channel)for my NHT VT1.4 fronts.

Any comments on this approach?
