Purchased on Amazon in early January 2024. I bought this to try it out, as I heard it was good for FPS games, while I was already using another DAC. The sound quality is flat, with no white noise on balanced connections, and I think it's a cost-effective DAC that can be used even with high-sensitivity earphones like the Ziigaat ARETE. However, I don't use it in my current setup, which combines a DAC and amplifier that cost over 100,000 yen, so I'm selling it to declutter. I think I used it for about 2 hours. I think it's good for those who want to try balanced connections for the first time, or for upgrading their FPS environment from a direct PC connection. (I think it could be an entry-level device for those who are into audio...) Thank you.
