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?

You can get a used Allnic L-3000 for about 4 grand. Dual mono, tube regulated, low impedance stepped attenuator, transformer coupled and puts a flat 150 ohms from 15hz to 30khz.

Amazing preamp.
Hello!
if you want to go for a low budget but good sounding go for the QUAD Twentyfour Pré Amp.

if money is not an issue go for the VTL 5.5 or 6.5
Browsing this thread with no thought of spending such money? You might be interested in this " Buyer's report: Xiangsheng 728A tube pre-amplifier " that I had posted on another forum.
Guys I have an EVO400 that came up locally... $4200 CAD
Also dealer selling ARC Ref 5 (consignment) $6900 CAD
Thoughts?
