Looking for a new (preowned OK) line stage under $5K: suggestions?

Considering upgrading my near vintage Classe Audio DR5 preamp, which I use as a line stage, for the following system:


Feickert Volare TT/Audimods 6 arm/Hanna ML cartridge, EAT Petit phono stage, Naim CD 5 disc player, Pass XA 25 amp, Joseph Audio Pulsar 2 Graphene speakers/Sound Anchor stands, Synergistic Research Foundation full loom.


Basically, looking to maximize dynamics as well as a touch more midrange bloom and dimensionality.  Slightly to warm side of neutral preferred over lean.


I'm thinking a tubed unit would work best, but I'd consider SS if it fits.


Also considering warmer cables, planning on swapping Xavfino's (Fusion) for the Synergistic's as a trial.


The basic issue is that the room is somewhat too "live" sounding, and my wife won't approve of room treatments (it's also a family room).


The system otherwise sounds great, and maybe within the described constraints, there's not much I can do effectively.


Input appreciated!


I recently purchased the PrimaLuna Evo400 line stage new. I could not be happier. Sound is awesome. Build quality is becoming legendary in the marketplace. They sell new just over 5200.00

Wyetech Labs Opal with 6SN7's is the best sounding preamp I've experienced (also the Ruby). Instant and noticable appreciation of the soundstage expansion and dimensionality.
