Back in 2019, I was very fortunate to get a first look at an extensive record collection from the estate sale of a grand lady of the Canadian diplomatic corps. As the refined collection of classical LPs were primarily monophonic, purchase of 100 of them was the perfect catalyst to dip my toes into the fabulous world of monophony.
First up was the need for a monophonic cartridge. I played many of the LPs with my reference stereo cartridge, the Phasemation PP-2000 MC Phono Pickup Cartridge ($6000). It did a very good job, if hampered a little by the specific geometry and physics required by the mono record groove. A cartridge wired and setup correctly for monaural with a mono switch on the phono stage lowers the noise floor considerably. But, that’s just the beginning of why a mono-specific cartridge can be so important to the vinyl collector.
