I own a handful of Outlaw M200 monoblocks. While they are wonderful for HT, they aren't really all that refined when it comes to music. They are excellent value for the money, but if you're going to bring such a highly regarded speakers as the HT3 into your rig, I'd definitely go with something nicer if it's in the budget.
If money is an issue, I'd consider one of Odyssey Audio's Khatargo amps. They have received rave reviews and can be had for around $750.
