If you like Classical/Chamber and Opera or Folk, I would get a Clearaudio Maestro Ebony V2 MM ($1200). If you like Jazz and Rock and Blues try a Dynavector 20x2 MC ($995). Either of these would be a excellent match with the RP6. Why you think going from a $1800 Apheta2 to a Hana (low output) is going to be a better thing is odd. I love REGA tables and these are the two cartridges I would buy If I owned a RP6 :-)
