I have a question whether the source of an audio file has any effect on the quality that you hear. For example, if I stream a song from my iphone to my stereo could it possibly be of lower quality than if I stream the same digital audio file from my computer to my stereo? Being that they are both the same digital audio file you would think it would be the same, but I think I can hear a difference. Is it the quality of the decoding of the file, the wireless connection, or something else entirely? Thanks a bunch.
