Turntable upgrade

Get a better phono preamp. I have the Rega P6  Exact 2 with an Aesthetix Rhea Eclipse. Sound is very special 

I had  a P5 with its RB700 arm and first upgraded the arm to the one that comes with the P8, the RB880. Huge difference (already had the TT_PSU). Subsequently I upgraded the table itself and actually like the look of it, although I must say the improvement in sound is not nearly as much as upgrading the arm itself. I assume you have the RB330 arm on the P6, so I would start with the arm if you don't want to take the full plunge to the P8.

Also, in my experience, Rega's cartridges are not nearly as good a value as their arms and tables. Try a different cartridge/phono stage combo, remembering to stay on the lighter side of cartridges. FWIW I have a van den Hul MC One special with a Sutherland Insight with LPS. I am very happy and the stylus on the cartridge lasts an especially long time.

Just remember to make sure the table is well isolated from vibrations. I put mine on top of a Townshend seismic platform which sits on a wall mounted shelf. My floor is suspended over a crawl space, and the sound improvement from putting the table on top of the platform/shelf combo was a dramatic improvement. 

I almost bought a P6 with Ania.  Had high expectations for the sound but it was one of the most disappointing sounding audio components I have experienced.  

Went with a Technics 1200GR and Audio Technica ART9 and what a complete treat this table has been. 

You might consider the Sota Quasar (or even bump it up to the suspended Sota Sapphire).

I believe both come with the Condor motor controller now.  (Could add the Roadrunner tach down the line).

Pick your own arm (e.g., an Origin Live  Silver or Zephyr).  or even stick with a Rega arm.
