I haven't heard the Ayre, but I have heard the Krell. Personally, I'd pass on the Krell, but that's me. The only way you will know for sure which YOU prefer, is to hear them both for yourself. If money is the real issue, buy the Krell. If money isn't the issue, go with the Ayre and be done with it since YOU know YOU do indeed like it.
Rarely do two people share the same opinion. If I had told you I heard them both but preferred the Krell, that would be no guarantee that if YOU heard them both that you would also prefer the Krell.
