I have a lot of mono albums,and wonder if it is worth it to get a mono cartridge.What are the advantages? I have heard that scratches are less of a problem and fidelity may be better. Is that all? I have a Dual 1229 with a mono /stereo headshell and can sum the connections to get mono sound,already. I currently have an AT95e stereo cartridge.Would I be better off just upgrading my stereo cartridge? Also, has anyone heard the Jeff Beck ,Truth lp from Sundazed, in mono?
