HT-X8500 Brand: SONY Purchased new in December 2021 at an electronics retailer. Currently, a new one is sold on Amazon for 47,500 yen. Used in a non-smoking household in the living room. There are no pets, so the condition is good. I checked the operation before listing, and the sound is working fine. I mainly used it for watching music concerts and didn't use it for regular TV programs. I'm selling it because I have fewer opportunities to watch music concerts and I'm organizing my equipment. I would like to sell it to someone who will use it well. I have the original box, so I will ship it in the original box.
