I Highly recommend the Outlaw 200WPC multichannel amps. I'm using a 7-channel version, the 770, in my high-end multichannel-audio system and I'm VERY pleased with it. They're available as 'B-stock' units often for a couple hundred$ less; mine looked perfect.
It uses an IEC-type removable powercord with the 20-amp connector at the amp, and those ARE available aftermarket. Also, you'll be pleased with its normal 5-way binding posts instead of those plastic-shrouded abominations that B&K uses (because the EU makes them because B&K wants to sell there). Sounds very good, too.
Read the reviews and BUY one. BTW I urge you to buy the one with two 'extra' channels, as you never know when you'll want to use them--I'm driving 3-and-2-half channels with 6 channels, biamping my Eminent Technology-12 centerchannel with dipole woofer AND the bass boxes of my ET8s.
