I can't answer Lewm's question but I do know my Miyajima Premium BE Mono cartridge sounds great with all my mono LPs. Unfortunately I don't use it very often because I have to switch tonearms to do so, and I am basically lazy.
I will take slight exception to some comments made earlier in this thread to the effect that playing mono records with a stereo cartridge results in a lot of noise unless you use a mono switch to parallel the outputs. I listen to many, many mono LPs with my Benz LP stereo cartridge without a mono switch, and most of these are just as quiet as my old stereo LPs. A mono cartridge (or a mono switch) will make the noisy LPs quieter, that's true, but I wouldn't want anyone to avoid playing mono records just because they don't have a mono cartridge or a mono switch on their preamp.
