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?
if you are patient, you can find a great Shindo in that price range.  A few Monbrison and Massetto models (both including a great phono stage) sell here on Audiogon in your prices every year.  you won't find a better tube pre.  Shindo's are exceptional

in same price range could also get an upper end Air Tight.

but to be honest, the rest of your system is so solid state high powered forward that I have no idea how the high end tube pre will blend with the rest of your gear.  might be amazing.  might not.

But both Shindo and Air Tight make exceptional tube Pre-amps.  Shindo being truly special.

There are others I could suggest. But those are truly amazing.

might also look at luxman, leben, Conrad Johnson, VAC

all make great tube pre-  


Take a look at AudioNote  UK --- it will be at the lower end of their product line - but their components are well worth the price -- if that is too rich for you look at Audio Note Kits Canada

I would back up the recommendations for either a Cary SLP-98 or SLP-05. Both are phenominal in my system, running into a Pass XA25, and can be had for less than 5k used.

I had a Rogue RP-5 before the Cary preamps and just like avanti1960 found it to be lacking compared to the Cary preamps with respect to dynamics, tone and timbre in my system.
