@Op I am not experienced in Clearaudio and I have owned two Regas.
Think of your vinyl playback as a stool
- Phono preamp
- Cartridge
- Turntable (and at some point you can separate into arm, power supply, etc.)
The turntable can make a huge difference - even staying with your current cartridge and phono stage and upgrading to Clear Audio, Project or even Rega.
I personally went with Rega because of its simplicity and I am not a tweaker. And that's the best thing and worst thing about Rega's; there's certainly more upgradability in other manufacturers.
And there's lot's of options for quality turn tables that can make a big improvement with out changing your cart of phono stage. Then when you upgrade your cart - you'll be getting increased value for the dollar spent.
