Vacuum tubes, block capacitors, etc. have been refreshed and maintained with attention to detail so that they can be used for a long time! You can enjoy the rich sound with stable operation. The fresh, glossy tone in the mid to high range has a different appeal from the MC275. There is a feeling of use such as small scratches, peeling prints, etc. (Murakoshi Yoichi)
