Is there life after a KXR? Help

I finally found the ultimate preamp. My own version of audio nirvana. The Ayre KXR. The trouble is I can't afford to keep it. So now I have to find a worthy successor. I'm especially interested in a tubed pre. If it has a great phono stage that's a huge advantage but not required. The rest of my system are Ayre MXRs, and Aerial 20t speakers. I've owned (and liked) an Ayre K-1xe, Levinson 380s, and I've tried using a Wadia system and forgoing the preamp altogether. I intend to buy something used. $10,000 is the top of my budget but I could eek out a tad more if I had to.
