Original owner, purchased new in August 2006, used in a pet-free and smoke-free dedicated sound room. Has about 400 hours of use on it. There is not a mark or scratch on the unit and it includes all original box, manual, and remote - so I rated is 9/10. Purchased a DP-800 DC-801 combination and use the DP-800 as a digital preamplifier. So this unit is now redundant. Complete with all original boxes, packing, manual, warranty card, power cord (un-used), remote, and Accuphase RCA interconnect (un-used). Yes this is a Japanese model originally set for 100 volts. I used it in my system set for USA 110 volts until I purchased a Japanese version PS-1200V. Now it is set to operate at 100 volts. I will set it to whatever voltage you desire (100 volt, 110 volt, 230 volt) - which is a simple single jumper. The manual is in Japanese but all functions are self-explanatory on the unit itself. For those of you wanting a deep-discount just because it is a Japanese unit, please look elsewhere. All shipping, import fees, duties, taxes, etc. are extra and must be paid by the buyer. THIS WELL BELOW A-GON BLUEBOOK AND WELL BELOW THE USED SELLING PRICE IN JAPAN.
