Garbage in garbage out. I think we need to focus on the source. The data sheets do cover some of the dac info. In reality I'm guessing any serious audiophile isn't going to remotely assume these devices meet their needs. Ceiling speakers aren't exactly audiophile. This is for over thinkers. Do some A/B testing with the same track using the dacs you have to see if you notice a difference.
I think people have more issues with speaker quality, line distance, acoustics, directionally, stereo vs mono etc than dac quality. My episode architectural speakers are mediocre at best. Still sounds fine for house music.
