Hey guys -- I'm trying to hone in my phono capabilities. Just cleaned up some 7 inches, readjusted the tracking force on the cartridge, and have come to realize I never experimented with my C-1's Phono 1 loading switch. My options are 0pf, 180pf, and 390pf. I looked up my cartridge (ortophon om 5e) and it says between 200-600pf. So I am just looking for reassurance that the 390pf setting is my optimal choice? I can defiantly tell 0pf sounds the worst, but not too much difference between 180pf and 390pf upon a quick listen? What do you think? Cheers
