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?

@smodtactical There is a bit of an underground group of Pass amp owners who've found a synergy running Cary Audio SLP-98 and SLP-05 preamps fwiw.  During a brief speaker building chat, Nelson confirmed for me he has many customers doing this successfully. Another option to the great suggestions above. I still run my SLP98, works well with many amps I've tried pairing it with.

The Cary SLP-05 is a smooth dynamic performer with a huge soundstage. It tends to be "phatter" and bassier, I really love the sound....


avanti1960,
Which 6SN7s are you running in your SLP-05 when you hear the "phatter" and "bassier" sound?

I was thinking your preamp came stock with EH. I ask because I can reproduce the same type of sound you describe with my own Cary SLP-98 preamp if I use new re-issue production Tung Sol 6SN7GTBs. As soon as I switch to NOS vintage Sylvania 6SN7s VT231s, or others like TJ Full Music / PSVANE 6SN7s, the top end opens up with more transparency, clarity, smoother detail, no more grain, and that "phatty bass" is no longer there like I hear with the new reissue Tung Sols.
