This is PLATANUS MC type phono cartridge. The connection from deep bass to high frequencies is good, and the playback ability is delicate and has a sense of density. You can honestly feel the vivid, dynamic sounds, and even the performer's emotions, and the records you've listened to over and over again until now will play richer and more beautiful music.
