Looking for warm tube preamp (should pair well with Pass power amp), budget $6000

Right now I have an ARC ref5se and its nice but looking for something of similar quality but warmer (maybe Vac, CJ or something you think will fit well). Looking for smooth sound, full mid range.



I use a McIntosh C2300 tube preamplifier bought new in 2008. I replaced the Chinese made "McIntosh" tubes inside it with NOS Telefunken tubes. I use it with a McIntosh MC2205 power amplifier. Very, very pleasant sound. 

LOL!  Nothing little about the SLP 05.

Same for the SLP-98. It's only little if you don't count the "loaf of bread" power supply. 

I think any Mac tube (or solid-state for that matter) runs on the warm side of neutral.
