I purchased this seeking the best sound, but due to my busy schedule, I only used it about 100 times before putting it away. ◆SRM-006tS Very beautiful condition. However, the power switch is harder to press than when I first bought it. There are no issues with the operation. Since this item has been stored away for a long time, there may be some oversights. As this is a high-end product, please feel free to contact me in advance if you have any concerns.
