EPC P202C is a VERY GOOD cartridge - and far too many "upgrade" from it - without ever giving it a fair try. Jico SAS with boron cantilever for EPC 22/202Cis the easy way out today - but I did the whole Per aspera ad astra yourney, back tracking and dot-connecting journey of Technics styli that are interchangeable - from BOTL to the TOTL, and know what various colours and line markings, if present, denote - even if the stylus itself is long gone. It took me couple of years to gather this information - the hard way.
In fact, to really upgrade from the EPC P202C, it takes one hell of a lot of money - MORE than normally paid for any SL linear table. EPC P205ED3 and '4, EPC P310MC (and MK2), EPC P100CMK4 - ANY of these, in ascending order, will run rings around the more usual suspects.
Grado P-mounts perform in SL linear arm really really well. If equalized, better ones can be stunningly good. These can be had for reasonable money - and are readily available..
