I'm selling this because I no longer have a use for it. This item was purchased new from a high-end audio shop in the past. It can be used as a speaker selector, but it can also be used as an amplifier switcher. I think this product will be useful for those who own multiple amplifiers or speakers. I used to have several myself, and I used this product. Included accessories are the original box, instruction manual, warranty, power adapter, glasses-type power cable, and dedicated remote control. The condition shows signs of use, but I think it's not bad. Please refrain from purchasing if you are concerned about the condition. This is the final price reduction, so I cannot negotiate a further discount. Thank you for your understanding.
