@hoytis When people ask me about tube preamps in this range, I don’t hesitate to suggest the PS Audio BHK Preamp. You can get them used for around $3200, and you can then invest a little bit into aftermarket tubes (the Brimar CV4003 are excellent in this unit, along with a few others) and a quality fuse (if you believe in them, as I do). Fully dialed in, I’ve heard the BHK perform against preamps twice its retail price.
In full disclosure, I am a dealer for many high end brands, but I have never had a professional affiliation with PS Audio. I was only a user of some of their products earlier in my audiophile journey. It took a $20K preamp to truly beat the BHK with the way two of them were dialed in to separate systems at separate times.
