Good call... I have used this table with two different stages; a harman kardon 3480 and a 12ax7 based preamp on loan from a friend. The glass preamp yields slightly better results but is still suffering from the same thing as the hk. I do know that this is the original cart that shipped on this thing in 81. I was leaning toward ortofon carts because thats the style this ULM arm was designed for. Any recomendations?
