People recommended SoundSmith cartridges made by Peter Ledermann (aka retipper on this forum). I asked Peter (SoundSmith) about vintage cartridges in this thread (quote below). You will see Grace in his list.
Me:
I’m curious, what is a well designed MM/MI or MC from the past (not new) in your opinion ?
Peter Ledermann:
Obviously Strain Gauge designs, although none have survived well, which is why I don’t work on them. Early Fairchild Stereo units. Some still are fantastic. Stax, for its cleverness, Dynavector 23 and similar, due to low mass (but terribly fragile), some Ortofon MI designs, Grace, and of course the B&O, upon which my line has evolved from. I have to say that as a person, VDH has befriended me from the beginning, and upon meeting and seeing my work, asked me "Are we competitors, or colleagues?"
I said it would be an honor to be considered a colleague; so he said "GOOT!" and shook my hand heartily and said - "What ever you need - always call me!" I have never taken him up on that, but I am always warmly welcomed by him whenever we happen to meet. The generous invitation was more than I needed or deserved. Indeed a gentleman and innovator, at a minimum. There is much to the man.
