I have the TT & Cart, had this same issue. Wanted my vinyl to sound better.
Here is what I did.....
Upgraded my TT with upgraded cable, alm sub platter, acrylic platter, Sumiko Moonstone, lastly hi-power power supply.
Everything helped a little, the cart was the biggest upgrade. Sadly the TT has a lot of noise, and no matter what will always be a low end TT.
Upgraded my TT to a Pro-Ject X2, with Amethyst cart & alm sub platter, along with a referb on my pre-amp. power supply & cable moved over to the X2. Everything is on another level, much lower noise, more detail, just sounds better everywhere. Sounds on par with my digital front end.
IMHO, to really get the big before and after, you need to spend 2-3X as much as you have now. Would say you are in the $1500-2000 range.
