Sound Warrior USB D/A Converter SWD-DA10 High-Performance USB D/A Converter Retail Price: ¥73,700 (tax included) I purchased this new online about 6 years ago and used it for about six months. Due to a change in environment, I stopped using it and have stored it in a dark place. I have confirmed its operation in conjunction with the SWD-TA10, which I am also selling. Everything in the first image is included; the box, instruction manual, etc., are missing. Also, one of the rubber feet is missing (see image 2). The instruction manual can be downloaded from the manufacturer's product page. (As of September 27, 2025)
