Artmat55, unfortunately while mono playback seems like it should have simple answers it can be deep water. For example, beyond the basic question of mono switch (in phono stage or preamp or via Y-adapter as Lew mentioned) VS mono cartridge there are more areas to consider.
If one elects to try a "mono" cartridge, is it a true mono design or merely a stereo model with channels strapped internally? I don't see that being different from a mono switch on a preamp. True mono cartridges do not have vertical compliance pick up. This means they can reject vertical groove noise. For example I've read that Grado mono cartridges are strapped internally, but I've not seen a confirmation of that.
Then assuming you choose a mono cartridge, does it have the proper tip dimension for the records being played? Mono records have varying width grooves depending on when they were cut and pressed.
Lastly is the question of equalization. While the RIAA curve was formalized around 1956 not all record companies adopted it immediately. Some mono LPs (and 45s) released in the '60s were still recorded with other EQs.
So what is a music lover to do? I think it depends on how many mono records one owns (how much trouble is worthwhile) and are those monos originals or reissues (post about 1990)? This has been a long way of saying if the only monos you have are the reissue Beatles then utilizing your mono switch with a stereo cartridge can be satisfactory. Not that they might not be better optimized but are the sonic gains worth all that trouble?
