The M&K 150's look to be a 4 ohm load, which would mean the 7100 would offer you about 165W/channel - which should do very comfortably indeed. I think any of Outlaw's amps would be worthwhile options to consider for your M&K's.
As usual, Gonk hit the nail on the head
My Father has an M&K 5000 THX speaker set up and uses an Adcom 200 Watt 5 Channel THX Amp, model number eludes me right now, as his power source and has absolutely no trouble running his set up.
I personally own an Adcom 100 watt GFA 545 II and I bought it new several years ago. My experience's with Outlaw and Adcom have brought me to this conclusion. After comparing the 545 and 7100 side by side, it is my opinion that any 2 channels of the 7100 are more powerful than the Adcom's, who is no slouch. A 7100 should run your M&K's just fine and a 755, 770 or 7 M-200's will
EASILY do the job.
