I wen't from the RP8/Apheta I combo, to the P8/Apheta II combo, and it's almost like night/day (though i hate that term used for Audio, but anyways). Some even claimed that the new P8 is better than the old RP10, so there u have it. If money is no object, then i would buy the P10 as an "end-game" TT. I think i will then be ok with the newer Apheta III, which in fact are the same "needle" as the Aphelion, but with another material for the body itself. Havne't heard the Apheta III, but from what iv'e heard, it's a freakin' bargain. If i can afford it, in the near future, i will settle on the P10 and be a happy owner for life.
