I'm driving my 3.6's with an Aragon 8008BB, and it sounds fine. It is also rated at 200 watts/channel, and, like the Krell, doubles its output power into 4 ohms. It's a lot less money than Krell or Levinson amps, though.
I have my 3.6's toed in so that you can just barely see the inner surface of the wood cabinet; that was the advice of the dealer where I bought them. I have them 7.5 feet apart, 3 feet from the back wall, 2.5 feet from the side walls, and about 10 feet away.
For what it's worth, the rest of my system includes the Denon 1650AR CD player, the Bryston BP-20 preamp, Pro-Silway II interconnects, Analysis Plus 0val 9 speaker cable, and the ExactPower 2000 AC correction system.
Good luck!
