I am a Rogue dealer and Joseph Audio dealer. The Joseph stuff matches up great with your amps. I would take a look at the RM7xl's or the RM22xl's (if you would consider a small/mid size floorstander). Of course, if you want to bump your budget up a bit, the Joseph Pulsars sound incredible with the M-180's.
