Any thoughts/experience with Rega Aphelion or Apheta 2 MC cartridges?

Hi A
I have a different turntable and arm so it's never a straight forward comparison. I have a Rega RP10 fitted with an Apheta 2 cartridge with a Unison Research Phono One valve pre-amplifier. This set up was chosen after a lot of blind listening demos at the dealer. The Apheta 2 cartridge got damaged (has anyone else done this?). Whilst it was being repaired by Rega (expensive but a good service) I fitted an Ortofon Cadenza Bronze and there was no comparison. Everything sounded flat and lifeless in comparison. It's a good cartridge but with the RP10 set up the Apheta 2 is clearly matched to give an open and detailed sound. I chose the valve pre-amp to add some warmth to the detail.  I would audition the Apheta 2 with your turntable. Hope this helps a bit.My question is - should I upgrade to the Rega Aphelion or will Rega be introducing a new cartridge soon?
All the Best

I am running an RP10 with an Apheta 2 and they definitely work really well together - tracks well, good bottom end, smooth but fast sound.  That said, I still miss my Lyra Delos which had an unfortunate accident with my now ex-girlfiend(yeah it's probably because she broke my Lyra LOL!). 

I can't say that I understand compliance well enough to confirm or deny if the Rega carts will mate well with your arm but if they're within spec they are definitely making a much better cartridge than they were in the past.  

I've tried MM's from all the usual suspects and on the MC side I've heard Shelter, Denon, the Audio Technica AT33PTG and besides the Lyra, the Apheta 2 has bested everything else that I've tried MM or MC.  I would imagine if you tried one and ran it in for a month you would easily be able to sell to someone with a Rega deck looking to upgrade without taking too much of a hit.
