I don't want to steer you away from this combo. I am familiar with krell and proac. The brightness of th krell combined with the brightness of the proac tweeter. Ouch! The proac is so easy to drive and the krell is such a beast. The beauty of the proac is that you could get by with the lower powered tubes. Say cary 805 or atma-sphere s30 or 60. Take your krell and match it with an aerial or some other hard to drive beast. The good thing is you can't go worng with any of these combo's.
