Shsohis,
Thanks for the update.
Glad to hear that you like it so far, even though it is a toss-up as to which is better, at least in the analog realm. (Not bad for a solid state unit, huh?! I agree that I too was somewhat surprised when I switched from a tubed preamp to the K-1xe as well.)
A quick question for you:
What cables are you using, and are they balanced or single ended?
(As you are aware, the Ayre unit, (and pretty much the entire line, to be honest), is designed from the ground up to use balanced cables.) Using balanced cables reduces the background noise slightly more, and it just plain sounds better, IMHO. And this includes the phono stage, especially since cartridges have a balanced signal, (although some prefer the use of the term differential to balanced when it comes to cartridges).
Let us know the ultimate outcome of your shootout!
