Thank you for viewing. I purchased this in February 2024 from a domestic earphone specialty store's online shop and used only the main unit indoors, connected to headphones with a balanced connection. I used it 1-2 times a month. It was always connected to a power supply, so I believe the battery is almost unused. I used the stand 1-2 times as well, but the other accessories, including the case, are unused. As far as I can see, there are no scratches. I am selling it because I haven't used it much. This is just my personal opinion, but I thought the sound quality when listening to high-resolution audio was very good, and I had no complaints at all. It is in excellent condition, but please understand that it is a used item and is sold as-is, with no returns or exchanges. I will ship it in the box it came in when I purchased it. Thank you for your consideration.
