Ayre K-5xe preamp? How close to K-1xe?

The K1xe is a right sizable step up. However, it would depend on the overall resolution of the system which I would choose. The K5xe is a good piece on its own standing. Just not up to the lofty standard of the K1xe.
Only you could decide if it's worth over twice the money.
I do not like the term "Blows away." Many are perfectly satisfied with the K5. The K5xe does not have the sonic resolution and transparency nor the dynamics of the K1xe.

Well, if you can, you should go to an Ayre dealer, and compare them yourself.

(That is the obvious answer, which probably is not an option available to you, or else you wouldn't have asked the question, right?!)

My advice is to post this query on Audio Asylum, in the Amp/Preamp section, and ask Charles Hansen directly, as he is a frequent contributer there.

(BTW, I love my K-1XE! And no, I have not heard the K-5XE. Sorry, but that would have been too easy!)

Good Luck!

Everybody here seems so happy with the K-1xe, I went ahead and ordered one today as well as the C-5xe Universal Disc Player. I will be using them with 2 Linn Klimax amps, and Sophia II loudspeakers. I hope I will get good synergy with that system.

Thanks for the responses, they were helpful in making my decision.
