To expand on my earlier comments. I think you have a very nice analog setup that should perform very well. Any significant upgrade will cost you significant dollars. I actually think your cartridge is probably your strongest element followed by the phono preamp, tonearm and lastly the table.
My recommendation is to stay with what you have. That said, Music Direct offers a VPI Classic Signature SE for $5,000. Alternatively you could also purchase a record cleaning machine.
