I'd put all three Salks on either a very good 3-channel, or 3 Monoblock amps.
I run my Salk-Cousin Philharmonic 3s on Outlaw 2200s, as well as the Center BMR + 2 Surround BMRs. These Amps work well; very well: I have no complaints.
If you wanted to go for some straight up numbers and you are running a balanced system, I would send you to look at the Nord/Apollon Hypex or Purifi based Monoblock Amps. Also, the ATI NCores are supposed to be very nice, too. If you are not in a balanced system, I would still recommend Monoblocks, but the choice really widens based on what you are willing to spend. That said, I suspect the Outlaw 2200s would still be very nice wit hthose SS 9.5s and the New SS Center!
