First, what are your system components?
Are you using the wireless feature or do you hardwire the TT to your system? And are you using the built-in phono preamp?
A different tonearm or platter wouldn't be the first upgrades to make on a table at this level. Upgrading the cartridge can provide a noticeable improvement in SQ. And using a dedicated phono preamp (phonostage) would also be a worthwhile upgrade.
