Opinions on Rega Apheta 3 or 2?


I recently got a good deal on a Rega Planar 8 and I'm now looking to outfit it with a cartridge. The guy who sold me the turntable has suggested Clearaudio Charisma v2 or  ZYX R100 Yatra H. Due to Rega not having a VTA adjustment, I'm leaning towards the Apheta line instead. Has anyone had any experience with any of the mentioned cartridges and I'm also welcome to other recommendations. I have a tavish adagio for a phono stage and both my my preamp and amp are tube based.

You can purchase shims/spacers for Rega tables that assist in changing VTA.  I have two P9's with Ortofon MC cartridges and use Acoustic Signature spacers with good results.

I am running an Apheta 2 on an RP10 and it's very good but if I weren't buying one at a discount with the player I'd buy something else.

Lyra or Dynavector at similar price points will best the Apheta - I was running a Lyra Delos prior to the Apheta and it worked amazingly well.  I would highly recommend trying one if it's within in your budget constraints.
Glad to hear, that third party options are great. There is a pretty good deal on a slightly used ZYX R100 and I might go with that. I also saw on the Rega website that they discourage shims and VTA adjustments don't make that much of a difference.
