Money well spent

Since your asking, cart upgrade vs TT upgrade, I vote for the TT. 

If your not rich......buy some albums and be happy. 

If your not going to do that, then upgrade your cartridge. Your table still has alot of headroom and can bring out much more with better cartridges.

Go Prime. I heard it about 10 months ago and was extremely impressed

Oleschool, it depends on what you want to accomplish. You will get better sound either way. But I think you want to upgrade the table, I would almost certainly do the same given the choice.

Nothing in an audio system will have as big an impact on the sound as the two transducers in the chain - the cartridge on the front end and the speakers at the back end.

So if your looking for the biggest sonic improvement right now, go with the cartridge.  A new TT would only be marginal.
