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

Well I assume you are looking for something that is not Pass.

Luxman or CJ are my thoughts.

PS Audio       BHK Signature Preamp.  $6600 new......$3500 used.

Buy it & don't look back.

PS Audio also takes trade ins.

Look for a 6SN7 preamp- will have much bigger tone 

Thanks so much guys for your many suggestions really appreciate it.

@fertguy  Did you find bhk sig pre to be a warm pre? From what i read its more neutral?

@erik_squires My understanding are the pass pre amps are fairly neutral sounding and of course SS so will lose out some of the staging properties of tube preamps.

@audioman58 Messaged don today. Definitely something im considering or maybe build the sp14 kit its based on. Not sure if his preamp is warm / rich.

@pesky_wabbit I'll look into that. I also heard changing the 6550 tube to Tung Sol from the sovtek leads to a much warmer sound. Going to find a Tung sol off ebay.

@ghdprentice @runwell  Interesting. Definitely didn't think of that. I wanted the power since my speakers are really not sensitive but ARC amps might work well. Are ARC amps more neutral and natural sounding rather than bloomy and wet?

@hilde45 Yup its not just tubes, the caps, circuit design, chokes etc can impact the tonal quality.

@rocray @cmach  Is Aric's gear warm sounding?
