I am going to second the excellent advice of the above poster and head you in the direction of an SP14, which uses 6SN7 octal tubes in its gain stage. It will be a bargain if you can build it yourself. I have a long term relationship with Don Sachs, who has taken the excellent SP14 and upgraded it with better volume pots, caps and other tweaks, and this version of the preamp, which cost about $1600-$1800, is the heart of my system. Insanely fine for the price, the pinnacle of preamps I have had for 45 years in my system.
Don's preamp recently compared favorable with my my audio friend's $10K ARC tube preamp in a comparison. I also have a stock SP14 with a Clarity cap upgrade, I would say that the stock SP14 is outstanding in every way, but Don's preamp is 50% better. I personally am of the opinion that a Don Sachs preamp and a great SS amp is your pathway to audio nirvana. I recently got a McCormack DNA .05 ss amp and with Don's preamp and my Spatial Audio Hologram M4 Turbo S speakers, I have never been so happy with the sound of my system. Good luck
