Regards, Hxt1: Shure recommends 4-500pF cap. At 100k Ohms res., hf/low level detail is quite good. Strong bass if VTA is slightly heel down, helps in taking bite out of the mids, too. Otherwise the Shure will sound brittle. Current passion is for a Signet TK5ea cart/AT155LC stylus, best when loaded at the other end of the range, 47k & 100pf. As you're probably aware, getting this right with MM's is a must.
Peace,
