Can't speak about durability yet but performance wise it's pretty good. I bought it to drive a low power in wall speaker. I also have a hifiberry AMP2 that I use to power some bookshelf speakers. As a test I connected one speaker to AMP2 and the other to this board and didn't see much of a difference. I haven't done an exhaustive sound quality comparison as they are not compatible with audiophile speakers. But for typical consumer-grade bookshelf speakers and low-to-mid volume levels, this board performs quite well. I hooked this up to a Raspberry Pi Zero W using piCorePlayer and it worked in about 5 minutes.
