I previously purchased this item, but I am selling it because I bought a different amplifier. This is a genuine domestic Japanese product, so it can be used with a home outlet. Everything that came with the purchase, such as the box and cables, is included. There are no major scratches, and it is in relatively good condition, but please understand that this is a used item before purchasing.
