You've got a nice system, as others have commented. For most people I would recommend something very basic like the Project Debut or the Rega P1 but that would be an insult to the rest of your system.
I just upgraded from the Rega P5 with exacta mm cartridge to Clearaudio Concept with Concept mc cartridge. For you this might be a great place to start. I would also consider the REga P6 or P9. Regas have great energy but the speed stability issues can be an issue. They eschew heavy platters because they think they decrease the energy in the music. The Clearaudio is definitely a quieter and more detailed presentation, but a tad drier than the REga.
The Clearaudio and the Rega are both pretty plug and play. Most other tables involve a bit more work, ifthat is an issue.
