Arthur, although it's good to be skeptical about things, there's no need for it these days with respect to the audio quality of digital disc players. At this and even lower prices players have for quite some time been outputting the data contained on the discs without audible flaws, i.e., with audibly flat frequency response and inaudibly low noise and distortion. Look to video processing features, but don't worry about the audio.
