First tube preamp recommendations (under $5k)


Right now have di20he -> terminator -> he9 -> pass x350.8 -> ATC scm7 / NS5000.
I am thinking of introducing some tubes into my chain. I like the sound I am getting but want to explore what tubes can do to the sound (slight warmth, biggest soundstage, better layering etc etc). Don’t want to go to nuts on price. If price is over $5k would consider if its really exceptional (but for sure not over $10k). Totally fine with used. Balanced would be nice but not mandatory.
So far I am thinking RP7, EVO400, bhk. Any thoughts?

Used McIntosh C2600 or a used Audio Research would be the way I would go.

Had a Pass XP22, it was excellent.  But I prefer my C2700 with the built in DAC.  Slightly larger soundstage, and the tubes add just that special something.

Note, used it with both my Pass 250.8 and MC462.  

While the amps were different, I noticed more of a difference between the pre-amps.  
Cary, Raven, AH Qualiton 20i, Quicksilver.... especially if $5000.00 is the hard ceiling and you are looking at Rouge, Prima Luna,.
You may want to look Hybrid like Pathos Logos or Dual Classic Mk3 in mono.
lots of choices.
Don Sachs


Don Sachs used to own one of space tech labs preamps, I believe it was the last preamp he sold after he started making his own, he only had one of the middle of the road space tech preamps.
Since you mention Don, his preamp would be a contender at far below 5K.



It is definitely worth the money, but I don't believe it would compete with the higher end model space tech labs stuff.
