Ayre V-5xe best tube pre-amp to match with?


I own an Ayre V-5xe power amp and strongly consider a very good tube pre - or the matching K-5xe pre amp from Ayre. Any suggestions?

Larryi: a friend of mine owns a Boulder 2008, 2010, 2020, 2050 set-up connected with TaraLabs Zero and Omega cords to a pair of Acapella Sphäron Excalibur speakers, cd-drive is Barclay X-1, turntable is Micro Seiki SX 8000 MK II - never ever heard music reproduction like this. Better than life like - o.k. the set-up is worth € 550.000,- but o.k. If the 865 integrated is at least able to reach 75% of the top-components - I´m very very happy.
I have had problems with four different pieces of Audio Research gear, so after 10 years of struggling with it, I changed to the Ayre-K1xe and I absolutely love it. to me the Ayre K-1xe sounds better than the ARC Ref II MkII preamp I traded in. And I am relieved to be rid of trouble. Try to listen to an Ayre K-1xe with your system. I think you will be glad you did. Tube woes can drive one nuts!
Frankpiet: I too am looking for a tube preamp to match the v-5xe and am looking to spend no more than $3K used. I have narrowed it down to 3: CJ LS 17 mark 2; Aesthetix calypso; and Hovland HP 100. I know that good results have been had with the Aesthetix and Hovland but has anyone mated the V-5xe with the CJ?
Russell..: in your case I would look for a late series HP-100. The Calypso was great in my system but the K-5xe with a few mods easily outperforms the Calypso except of the lowest octave and pin-point imaging (all Ayres I know miss the punch in this area).
