INFINITY NEW! “INFINITY MONO” made heavier than ordinary cartridges to pursue ideal. It is a size outside common sense. The size of the body is W 24.0 mm x D 28.6 mm. The length of the terminal is 4.0 mm. Please check whether it can be used for the tonearm or headshell you have. That sound expresses unprecedented low tone volume, clear, three-dimensional, and instrumental quality. It is music, not audio. This cartridge is special. The wiring of the terminal of this monaural cartridge is the same as ordinary stereo cartridge.
