Bill, I've been using my 501 on my Garrard 401 for around fifteen years now, and I've used quite a few different cartridges on it, without problems. I don't claim to be knowledgeable about analog details, but I do know the 501 arm will acomodate many diferent cartridges without presenting problems.
The table, arm and cartridges are getting old with me, but they still satisfy on a daily basis.
Best regards,
Dan
