@ricred1 there’s another similar thread about preamps that you are aware of and you are also aware of my recommendations for Mola Mola which based on European prices would certainly be within your budget.
Preamps
I'm not unhappy with the Jeff Rowland Corus preamp, but I don't know what I don't know. I'm currently looking for a solid state preamp with HT bypass to compare to my Jeff Rowland Corus preamp. I would like suggestions below $15K new list price to listen to. I have a Jeff Rowland 625 S2 amplifier, Antipodes DS GT music server and Chord Dave DAC.
