Pre amp replacement?? Help

If you aren't using it for theater there is a lot wasted in the pre-pro.  A dedicated 2 channel pre would be an improvement.  I'm guessing that since your table isn't really working that you either use radio or digital?  If you need a tuner then look at a nice receiver with pre-amp outputs for future upgrades?  If you use a digital source then a pre-amp with a nice dac would do wonders.  A peachtree or similar would be nice and clean.  That's your first $500 (less what you sell the sony for).
Next would be a cartridge.  You don't need to spend a fortune.  Lot's of choices in the range of a Shure m97 that will get vinyl going.  Check out needle doctor.  
That's where I'd start, I think

Thanks for the response. I’ve gotten plenty of wonderful years from the Sony, but you’re right, I’m not using it for all it’s capabilities now. I just ordered a new stylus for my Grado MF 3. I may sell my MK Cotter as well. That should give me a nice budget. I do digital and hi res audio music. A nice pre amp .. yes

Just image the compromises when building a $1000 pre-pro.  Now take that same budget to build a pure preamp.  I'm not knocking Sony ES.  They are nice.  You will be better served with a 2 channel system.

Agreed ! If I budgeted for 2k what are my good choices?

The Sony does a a direct 2 channel bypass however
