Hello,
The Rega P6 TT is a great turntable for the money. If your cartridge is in good shape and has life left in it I would go with the PS Audio Stellar option. I believe they let you try it before committing to it. Also you can trade in your old Phono stage to ease the money after you do an A/B comparison. If you do not like the Stellar. You can move to the cartridge which will not be returnable.
