Dennistran, here's the answers to your two questions:
1) Pass Labs XA 160 monoblocks do not double down as impedence decreases, so they would drive your 802's, but a better match would be the new XA 160.5's that do double down in lower impedences and offer more current. I own Pass Labs XA-100's and love their performance in my system. If you want more information on the sonics of the XA amps go to my review here on the GON.
2) Based on my personnal taste I find the Pass Labs XA amps much more "musical" with much more liquidity then the ML amps. I just recently listened to the ML amps again, and still find the XA series amps to offer much more to my ear's what music sounds like.
