Sherbourn PA7-350 any thoughts

I currently have a older version, the Sherbourn 7/200 and am thinking of either upgrading or keeping both amps for a bi-wire of my 7 speakers.

I realize that bi-wiring sides and rears may be overkill, but all the B&W speakers are bi-wire capable and the older unit would not have much resale value.

The only issue I would have is that one speaker, probably the Center Channel would have to have a connection from the 2 amps.

The Unit is currently on sale at $1,959.00 down from $2,400.00.
Not sure if that is a prelude to a new Amp, it is hard to judge a stereo review and I generally prefer real world usage.

I use my system for an 80/20 video to music ratio.
