Kharma 3.2.2: which tube amp to use?


After living with Kharma 3.2 and now 3.2.2 for 5 years with SS amplification, I am looking to try out a tube amp. My current amp is Goldmund Telos 400 (being put on sale on A’gon). My preamp is Vitus SL101. My room is 10’ x 14’. My source is a TW Acustic turntable. Current sound is fast, highly detailed, with great imaging. But on the dry and analytical side. I hope a tube amp can fill in some of the missing midrange harmonics and timbres, add bit more air and bloom. Add bit more flesh on the bones.
I am looking at SET amp and not sure which one will drive my 3.2.2 (90db, 3.5 – 4ohm) without giving me loose bass, and also not too much heat (considering my smallish room). I read Kharma 3.2 was voiced with Lamm (don’t know which model).
Your suggestions will be much appreciated.

My next speakers will likely be Kharma 3.2's. I am presently using an Art Audio Carissa Signature (18wpc, 845 tubes) with Merlin VSM-MM and Superbam. I believe the Kharma and Merlins present a very similar load to the amp (Kharma may have slightly lower impedence across the board), the Carissa Sig. is wonderful with the Merlin, bass is easily controlled with a synergistic setup. I hope to try the two together in the next year or so.
I have a Carissa running into a pair of 89db VS VR4jr and the Carissa does a very nice job. The Carissa would help your dry midrange. However if you would like something even better look into the Art Audio Vivo. The Vivo would have greater dynamics with a very sweet midrange. It's like a Carissa on steroids.

Forgot to mention the Atmosphere line of tube products!

Thanks folks for your suggestions. The research is still on.
I happen to read about the two-chasis Artemis Labs SP-1 stereo amp of 18W 300B based SET, which garnered high marks with the TAS magazine. Has anyone had first hand experience with this amp and could share?
