Has anyone compared Ayre K-1x to Pass X-1


I am considering buying one of these two ss Preamps and was curious if anyone had had the opportunity to compare them. I am using Pass X-600 mono's to drive my Amati's. Which of the two are warmer sounding? If anyone can give me an idea of the basic sonic differences between the two I would appreciate it. Thank you for your feedback.

Why is Superphon a "flake" manufacturer? Can you enlighten
me on the subject? I had no previous experience with this company. The ref2 remains in my collection of audio equipment..I regret selling the CAT pre..

Damn, what a cluster_f%$k this Stan Warren and his Superphon is! Thanks for the warning
Hello,
I thought I’d throw in my .02 about my experiences with my Pass Labs X-1. I bought a refurbished (and spotless, a 9+ here at Audiogon) X-1 from Reno HiFi and could not be happier. It truly was (and still is) goose bump moments when I’m listening. My soundstage has exploded. The music is coming from behind my speakers, to the left, to the right, and in front of. I guess that’s what they mean when they say your “speakers disappear”. There is more “space” between the instruments. I can't honestly tell if it is "coloring" the sound at all. If it is, I sure can't pinpoint the effect.
My previous preamps were a Belles 21A and a Creek 5350R. The Belles was quite nice, but the Pass is definitely a big step up. The Belles did have a more “tubey” sound.(If I discuss why I didn’t like that “tubey” sound, a posting war will probably follow, ha!)
I’m sure my X-1 will be in my system for a long time and I’ll upgrade the other components once or even twice before I even consider upgrading the X-1.

Tgyeti, I just got a new-in-box X1 for a decent price. Haven't received it yet. What are your impressions of the high and low end extension, transient speed, and clarity of the music? I've heard the X2.2 and thought it was pretty darned good in these areas without giving away any musical realism.
