You should be able to find a Doge 8 preamp within your price range, depending on the tube set it comes with..
I had one before I replaced it with a Don Sachs preamp.
The Doge 8 is *very* sensitive to tube selection (4 X 12AX7, 4 X 12AT7). I really liked the sound that Siemens ECC801S and Mazda 12AT7 tubes gave me.
The Doge 8 also has a very decent phono section (both MM and MC). If you don’t spin vinyl, then you can put any cheap 12AX7 tube in.
