My Integrated can handle MM or MC carts it is full adjustable by dip switches inside on the phono card. It is however fixed at 50 db of gain. This is the newest Modwright integrated, KWH 225i.
After looking at the Soundsmith website it appears all their carts like more gain than I have available. They say 58-64 bd for gain.
I have had the TT checked by a competent local tech and it is in perfect spec and near perfect cosmetic condition. I have it setting on its own steel table with a 1.75" maple top. (made from a piece of industrial equipment extremely heavy on a concrete floor) It is level and not moving short of an earthquake.
Thanks again for all your comments.
