To me the "source" is the recording itself. That's the biggest quality factor, and everything else is way less important IMO.

Thats a good point Ethan, and can even apply to CDs.
I find quite a lot remasters to be incredibly disappointing, well dog **** would be a better word.
And then there are those recordings-mixing/mastering that take loudness wars to new levels such as Metallica and others; in these cases it does not matter how great the system or room is IMO
Thank goodness Guns n Roses (example of a mainstream-ish band taking notice) took the opposite view and went with a dynamic album, ironically though Metallica's album won many awards even after being criticised by industry mastering engineers for its loudnes and compression sigh.
