My all time favorite MM/MI was a Sonus Blue Label (on an LP12/Keith Monks arm in the mid-70's). l recently found a NOS Grace F9 Ruby, fitted to my WTTT/WTTA, but I'm eyeing a new toy...Sumiko Amethyst or Grado Master3 or maybe a Benz Micro Ace H. Anyone with thoughts on these? My preamp is a C-J PV11 (47 dB MM gain).
