This is depressing.
You have to wonder how these PCM tracks would fair if they were converted (Torn? Un-ripped? Pired?) using an Ayre QA9 or something similar. Perhaps the greatest difference between PCM and DSD is the filters used - or not used - in the process. Better filters might make all the difference. Or, maybe they do but there's more to the story as well.
Are we back to buying really great vinyl, playing it on a really great turntable/arm/cartridge/phono preamp and piring it all with a great A/D just so that we can get really high quality digital playback? Think of the hobby hours one could devote to just that. Nobody would have a minute to read Audiostream.
