The price has been reduced. 2022/5/5 selling price 29,800 yen An MC head amplifier that powerfully boosts orthophone cartridges with low output in the past. The gain is as high as 34 dB, and the sound comes forward (normal MC boost is about 26dB). Can be used with any MC cartridge without being affected by impedance. An easy-to-use model that also has a PASS function and a subsonic filter function. The appearance is small scratches and dullness (Kanai Hidetsugu)
