B&K pairs great with Klipsch. The ST-125.2 (now badged as Reference 125.2) is more than sufficient & you can pick them up dirt cheap on epay - don't worry about buying used, they're pretty much bullet proof.
As you can see from my sig. line, I'm a B&K fan. BIG step up from my previous Carver based system.
