Phono stages are extremely critical in getting the sound your turntable and cartridge are capable of creating. I definitely recommend tubes to get the full musicality.
You have a very high quality turntable and cartridge so I recommend a phonostage from Audio Research (my favorite), Conrad Johnson, or Presto. However, I would save up. I would invest something on the order of the value of your turntable.
To get most of the capability from your TT I would recommend a used Audio Research PH8. Better would… well be better. But given the really low number you threw out this will get you 90% there.
