If you can stretch for it, try LS footers for speakers from critical mass systems. They decouple your speakers from the room in a wonderful way. In my system they removed all traces of edginess (yes edginess) and boom. Their CS footers for electronics and TT's are no slouch either. A single set of these under your TT may give you a relatively cheap upgrade that would obviate the need for a component upgrade. I say may, because I don't have a TT, so my experience limited to what they did with electronics. Check reviews.
How do you know what your weakest link is?
I'm contemplating what to upgrade and need some advice on what my weakest link is? I'm considering either upgrading my Clearaudio Concept Wood to a Performance DC Wood/Ovation with a Hana ML or upgrading my Musical Surroundings Nova III to a Modwright 9.0. Is my table the weak link or is my phono? What will my best gain come from and what should I expect that gain to manifest as?
