I’ve mentioned before that I get pretty excited whenever I hear from Yoshi-san & Elia-san (father & son) of the MuSon Project in Osaka, Japan, who export Japanese audio exotica to The World, because it means that something exciting is about to happen audio-wise! Yoshi-san told me that he had a new phonograph cartridge that he […]
