The P3 has a RB300 'arm - RB300 (and RB600) are stock from Rega with end-to-end interconnects (I have the 600, which uses different cable and Neutrik Pro-Fi RCA's). I suppose the argument is it provides one less connection to color the low level signals of cart to preamp. But then there's the joint between headshell leads and the interconnect wire...so I'm not sure of the real logic there.
But I'm pretty sure the only way to modify is major surgery.
Expressimo Audio (the Heavyweight guys) does an end to end upgrade - cart leads to interconnects, but it still includes interconnects and RCA's; The Analog Room in San Jose modded mine with VDH silver terminated in a DIN at the stub...so now I can try different DIN-to-RCA phono cables.
Probably the best upgrade (I'm told) is to send the sucker to OriginLive for their full blown modification.
