I just purchased the Edifier s2000 mkiii speaker set. I find the sound is greatly improved with a dac from my computer or tv optical out dac. With a outside dac the sound is much better than the internal one. The optical cable which comes with it is inferior and the electrical cable is short and very thin. I use this to improve tv and have a much better stereo and speakers in my listening room. This is my first experience with powered speakers. The sound overall is not impressive but ok for tv and some Bluetooth music. What is frustrating is the forced dsp of classic, vocal, dynamic or monitor. Is there some way to turn dsp off that someone is aware of? Thank you
