Here's a different idea. Don't invest any money in that table. If you're not happy with the way it sounds now, buy a better turntable.
I started out with a Music Hall 2.2, added a the speed box, put on an acrylic platter, and put a couple of better cartridges on it, including the current one, a Nagaoka MP-500.
A Music Hall 5.3 or 7.3 with an inexpensive cart like the AT95 will sound much better than the 2.3 will with an upgraded cartridge. I currently have a Music Hall 7.1 and with an old Shure V15 with a JICO SAS stylus it sounds way better than the 2.2 with all the upgrades I did to it. I had an AT95 from another table I had and have mounted it on the 7.1 and it also sounded better than the 2.2.
The 2.3 is an entry level table - it doesn't have good motor isolation, it doesn't have much mass, it has a cheap tonearm, and the feet are pretty cheap.
Either be happy with it as is or get a better table.
I'm not saying it's a bad table, but buying a better table will give you more bang for your buck if you're looking for an improvement in sound quality.
