Cheers to you as well, JP.
Just to bump this thread, which to me is more interesting than "what cartridge to use on a Reed 3P?", I will add after another night of listening to a wide variety of LPs, good and mediocre in sonic quality, that this combo of TT101, SS300 mat, FR64S tonearm, and Acutex LPM320 cartridge is THE quietest vinyl set-up I have ever heard. On better LPs, one could easily convince oneself that one is listening to a CD, except unlike CDs, which have a "noiseless floor" that seems to lie above the musical noise floor, this combo gives you ALL the lowest level musical cues (which CDs mask, usually). On top of that, you get that fluidity and effortlessness that I now think may be characteristic of coreless motors (and the SP10 Mk3 with Krebs mod). I am going to try other mats, of course. For starters, I can borrow the Boston Audio Mat1 from my Lenco, which is sitting next to the TT101. If I can find a pigskin, I surely will try it. And I may shell out for the reproduction of the CU-180.
