The vintage NAD gear and Klipsch speakers made great matches when I was in college. I've never been that big a fan of Adcom- too polite. A friend in OK uses Carver's "The Receiver" with Heresy II's and loves the combination (he switched from Adcom). One of Parasound's smaller amps and a CD player with a volume control would also be a good option.
Remember, with Klipsch, you won't need much power to get loud. Look for good watts, not many watts.
