Your mix might be a little anemic sounding, especially without tone controls with klipsch speakers, they are good speakers for the dollar but need some good combos to make them really sound right, I had klipsch for years and commend the basic design and type of approch they make, but you may need to go with different amplification for them.. To the question on Krell, well my opinion really does not matter but none of the stuff I tried impressed me, I like much more Organic, musical sounding stuff, not necessarily super accurate.
