If I were in the market for a Phono-Pre, I would ask for advice, read reviews and make a SHORT LIST OF UNITS TO DEMO.
Because the transducer (cartridge) feeds the phono-pre, it may even more important to to demo phono-preamps than line-stages and amps (yes, these are also demo-ing, if possible).
That being said, I am very happy with my Zesto Andros, which I have had for many years (I have no affiliation). In fact, I may upgrade to a newer Andros version in 2025.
You should be able to find a good, used Andros in your stated budget. Add $150 for four new tubes, and you should be satisfied for many years to come.
Best of luck with the search.
