Any suggestions to power B&W 801S3 speakers?

I am currently bi-wiring two McIntosh MC7150 amp with C-40 preamp.
Pass Aleph 1.2 monos
Any older Threshold . S/300 - Sa-1 monos etc...Great match
The Krell FPB700cx is a synergistic match with the 801s.3 speakers. Add external Northcreek crossovers for the best sound I've personally heard from any system.
