which HT processor of these three?

50/50 music and movies
system is all B&W, 801's, 804's, ASW800 sub, B&w center,
already have balanced custom b&w mono amps for the front channels
will also need 5 more channels of amplification (so if you would like to add your 2 cents worth about multi channel balanced amps, please do)
DVD/CD/DVDA Marantz 12S1
currently available on audiogon
**Krell HTS2 upgraded to 7.1 (asking 4800)
**Integra Research SD7 latest with bass management(ask 2800)
**Aragon Stage One (asking 2800)
need to stay balanced, want 7.1, and prefer some base management
also like the classe 60, but none available at this time
thanks for the help
