On the Cartridge end, I have been persuaded by the opinion that vintage cartridges from the 70's and 80's are comparable in quality to the some of today's more expensive offerings. One of the project right now is to seek out a vintage cartridge, something like an Ortofon MC 2000, to pair with the SME V.It's a fallacy.
The likelihood that a cartridge suspension still operates correctly after so many years is close to zero. I would not subject my valuable record collection to the abuse from a clapped out cartridge just to save a few dollars. The damage on vinyl from mistracking, even unheard, is massive and permanent.
Unfortunately there seem to be a few on this forum who promote vintage cartridges, but the reality is that finding a NOS example or new stylus is almost impossble for most of them ( some on this forum are resellers of clapped out cartridges - buyer beware ), and ultimately more costly than a reasonably priced modern cartridge.
