looking for a tube preamps that doesn't sound like SS


any recommendations for a tube preamp under 4k, that has old school sound, warm, fat, with good mid range and sound-staging.

I have a good SS set up, good clarity and imaging but would like to change things up with a good tube,.

Dennis Had makes some great sounding preamps the Inspire LP-3.1 is his newest,I think.He sells them on Ebay. You can use 6SN7 or 6SL7and it is also reasonably priced. A tube rollers dream if you like to do so. 
I had Audio Research SP-6B, and Joule Electra is far better
Old Conrad Johnson have nice tube sound but not have dynamic like Joule
Any Conrad-Johnson pre-amp although they are pricey. The PrimaLuna Dialogue and Dialogue Premium are an excellent value and do sound lovely. I'm sure their EVO series is great as well.
Both brands are wires with gain and multiple inputs.
