Amp for Kef reference 1 -Ayre Acoustics AX-5 0 Match?

All of the integrated amps you mention will be more than $5K.  You might want to look at the new Belles Aria Signature integrated at $4495. It's a great sounding amp and seems to be able to drive many speakers. I have heard it with Vandersteen, Proac and Magnepan speakers. 

JohnnyR at the Audio Connection can help you with your search. He is a Belles and Ayre dealer.

Joey the belles integrated sounds awful on kefs we had a client bring his aria to demo on kef r11 the combo was not good what sounds good on a warm speaker such as a vandy is not going to work on a more neutral kef

The coda csib is probably the Best sounding sub 10k integrated and it is a phenominal deal the amp in the integrated is exactly the same as the award winning coda.8 which sells for the same price so the csib integrated is basically giving you a free preamp

the ref 1 coda csib combo
is fantastic we have a client with that exact pairing

@audiotroy:

You could be right as every Kef Speaker I ever heard sounds like drek to me. But that's only my opinion and everyone hears things differently and no one is right or wrong in their opinion, including me. I know there are many happy KEF owners out there so they must sound good to some people.

Audiotroy, have you ever heard the Belles Aria SIGNATURE, Yes or no?

Joey yes the client brought it in

Hate to Break it to you but we have some serious doubts about your hearing kef builds some of the worlds Best loudspeakers and they are tottally acurate and if you use the right gear they sound amazing
