In theory, I side with Doug and Dertonearm. In practice, I think I can "hear" connectors with MC cartridges and not so much with higher output MM and MI cartridges. I empirically assign blame to the low output of the MCs in question. However, the contacts I/we are usually dealing with are either DIN plugs at the base of the tonearm or the horror of a headshell, which can actually add three sets of contacts in the signal path, one at the cartridge pins, one at the rear of the headshell itself, and one on the other side of the headshell, where it mates to the tonearm. This is indeed a "worst case" scenario. However, I would not categorically say that it is impossible for Mr. Graham to have implemented contacts that are relatively benign in their effect. I'd far rather have one set of contacts at the pivot end of a replaceable arm wand than 3 sets at the headshell end.
