jolaca,
I now have a pair of Bryston 7B SST driving the front two 802's.
This means that the 250x3R now drives the centre HTM1 and the surround 802's, leaving the Marantz monoblocks to drive the rear 805's.
When I can figure out how to bi-amp the rears, I will use the spare set of Marantz monoblocks to do this.
BTW the sound has improves so much since the change and the Brystons have not yet "run in"
