Ayre K1xe vs. Simaudio P7, P8


Has anyone had a chance to compare the Ayre and one of the evolution Sims? I realize that the P7 and P8 are more loaded with gadgetry and cost quite a bit more, but my question regards only sound quality and presentation. Any reliability/ quality control issues? I appreciate any experience you care to relate...

I do not remmeber the exact McIntosh models. One was the newer integrated that I think cost around $7,000 if I remember correctly. The other was a McIntosh amp and preamp. The amp was a remake of an old McIntosh and the new version had garnered praise in a couple of audio mags. The preamp was a McIntosh but for the life of me I cannot recall the model number.
Bluesnzzz: The thread helped me discern my bias for Simaudio, a type of bias often merely "reinforced" by firsthand audition.

Admittedly, I'm quite sure that I'd be very happy with a K1, and I'm glad that you are with yours.

(But can we really conclude that none of these other fellows has heard the K1? ;)
Has anyone compared a Simaudio P7 with a McIntosh C50 or C500? I know that the feature sets are different, but what about sound quality.
I have to run balanced and the Ayre is on my short list. Basically, the only other pre along with the Ayre I'm considering is a newer VAC renaiissance.
