What are the more subtle sounding tube preamps?

Huh? Earlier ARC’s were way too analytic and cold for me. Newer ARC is much warmer to my ears.

Personally I the new ARC sound for being less clinical and tons warmer, without being as euphonic as the earlier CJ's.

I haven't actually heard modern CJ gear in forever.

Having owned ARC gear for almost 30 years now I have to agree with  randy-11. Older ARC gear was more lush and tubey sounding. Closer to the Conrad Johnson type sound. Modern ARC is far more detailed and holographic with less tube warmth. Some pieces such as the LS27 can even sound a bit thin at times. The Ref preamps have a bit more warmth while retaining that detailed holographic sound.

Yeah, I think less "lushness" or "bloom" is what I'm looking for.  Somewhere b/t tube and SS I guess. 

The Aesthetix Calypso is a very good, not overly lush tube preamp.

The Audio Research Ref 5se is a real bargain for what it sells for used. Still one of the best sounding preamps available today.
