help with a tubed integrated or pre / amp combo


So ... I used to have a audible illusions 3a and a Conrad Johnson 11a combo which was a very good match for my energy veritas 2.3s. I downgraded to a cayin a 50t which is nice but a bit under powered for my speakers. what integrated or pre (with phono) amp combo would be a good upgrade for me at 2400.00. I listen to a lot of female singers like Nora Jones, Allison Kraus, classical and world music. My listening room is a hard wood suspended floor with plaster walls. I've tried some solid state set ups prior but never worked with my room and system.

How about prima luna, mystere, and Jolida. They all make good tube amps in that price range. They all have informative websites as well. Also I forgot about rogue audio as well. If u like vintage tubes, Mcintosh and Dynaco make very good tube amps also.
go for the cayin 100 or 88, great sound, great value. I have both and have been very pleased.
