Never tried these but they seem to be quite popular with people wanting either a cheap cart or something to play boot fair records with.
The Rega Carbon.. It's a Audio Technica AT91 but branded Rega and with a Carbon cantilever. Don't think there are any other changes?
It's a cheap spherical tip hi-fi cart, only thing is the low 2.5mv output.
They look cool and are very cheap at £25-30 a pop, this is what the Shure M35x also used to cost before the price hike :-(
I'd like to try one but not sure why, pretty sure they won't even touch a Stanton and the M35x is still a better cheap modern day choice over any Ortofon imo if all you want to do is play/mix music i.e. no crazy Q Bert shiz
