Serious question on audio quality
If you have a digital format audio format, with a 'quite well' documented decoding routine (PCM/AC3/DTS/DTS-MA) piped over a digital interface like HDMI.. how can sound differ between devices ?
You also don't compare PC quality by decoding a ZIP file and see which decodes it 'best'. It does it correct or it is broken.
So are you talking about analogue audio quality, or am I missing something completely here?
