Dispelling a myth (?) about phono-cartridge loading
In the midst of his December 2023 Gramophone Dreams column, Herb Reichert presented the results of an experiment. He was listening to the most recent version of Zu Audio's Denon DL-103, installed on his new-old Lenco. He hooked it up to the moving coil input of his SunValley SV-EQ1616D phono preamp, which apparently is intended for use with low-output MC cartridges since it loads them down with a 50 ohm shunt resistora heavy load for all but the lowest-impedance MCs. The rough rule of thumb for loading an MC cartridge, as many readers are aware, is that the load resistance should exceed the cartridge's internal impedance by about a factor of 10.
