This is a the US version of this amp. It is not a gray market Japanese import and does not need a voltage transformer. I purchased it from an authorized US retailer. It has been in a nonsmoking household and I am the only person that has ever touched this Amp. It includes everything that was included when new including the factory double boxes, remote, manuals, cables, etc. It is perfect in every way with no cosmetic or operational issues.
This is an EXCEPTIONAL amp that is pure class A power at 20 WPC. It has however been measured in some publications as more like 60 to 80 WPC though I can't verify this. What I can verify is that I have never been able to turn it more that 1/3 of the way up without it blasting me out of the room. It plays and controls my B&W 805D3s perfectly with plenty of authority and bass. It is built like a tank but with the attention to detail of a fine watch. You will not be disappointed!!!
