Did I make a mistake buying Krell?

I don't man, I would be really nervous about your decision if I were you. You may want to go to some other forums and ask them what they think before you hook things up.
GOOD GOD.

I owned a KAV-300i for about 6 months. I really tried to like it but it always came off as sterile. It lacked the warmth I prefer and perhaps what others call "neutral". It did dredge up bass that I did not know was with in my speakers, it was quick on transients but the highs seemed edgy. I had it matched with 90db monitors (ACI Sapphires).

I feel it may well overpower your klipsch and that you never get the full benefit of its excellent power. Heck, it may never even get warm.

My experience only-your mileage may vary.

I had KLF 30's with a 300i for two years. Then I bought a pair of B&W DM 602.5's & I never looked back. Where you made the mistaken is buying the klipsch. Knock on the side of the cabinet that ringing sound you hear is not quality.

Krellm7 I will have to agree with you on your choice to pair a Krell amp with B&W speakers as I have a close buddy on Audiogon that has this set up & loves it. I don't agree with your asessment on all Klipsch speakers as the different models are not all equal in sound or build quality. I have the Klipsch CF4s which were next to the best Klipsch speaker sold in the early nineties, you will never see me sell these. The McCormack amps sound excellent with Klipsch speakers as I found out, also Steve McCormack mentioned to me in a phone conversation that some of his customers felt the same way. I am not dismissing Krell as a good power amp as I never heard one but rather making a suggestion as what works well & sounds good with Klipsch. I love well designed horn speakers, someday I hope to purchase Advantgarde. Vman71, let us know how things work out.

the krell is your keeper. hook up and play.
