nad processor I’ve had experience with has an interface that’s very easy to follow and not glitchy. Although still most interfaces have their quirky qualities because the people developing them have no insight into what mere humans experience when faced with a learning curve.
As for the interface related to DSP, it’s terribly horrifying it should be a lot easier it’s not like it’s doing terribly complicated things. You can only save 3 DSP settings on a nad processor and that’s really disappointing.
Again the real problem is just the compressed streaming Quality that’s offered and that’s inherent in the environment and that’s going to limit progress creating better processors which probably could sound a lot better where not for the terrible compression movie soundtracks that exist. you would think with 5G and better bandwidth on pipes compression would be less of an issue but it remains the single worst issue facing quality sound for people who stream.
