You have many choices with the adjustable gain on your 1201. I don't know what the best would be but I have used a Dynavector XX2 MKII with good results. A couple others might be a Shelter or a ZYX. My 312S is on an Technics SP 10 MK II with the Krebs mod mounted on a plinth I made finished with Brazilian Koa.
