Carlos,
Maybe you should replace the word "pretentious" with "generous" or "gracious" in your thread title. Thank you for responding so quickly and thoroughly. I have a vague and rudimentary understanding of the very broadest aspects of what you're describing. Case in point: The original "Cars" album, as mastered by Steve Hoffman on gold disc on the DCC label (catalog # GZS-1032) is one of the finest sounding CD's that I own, and its release date is 1995. He's apparently a very well regarded mastering engineer.
I've neither the time nor the financial wherewithal to pursue your path, but have been fortunate enough to nevertheless make it off the merry-go-round, thanks to the Intuitive Design Summits. Still, it's intriguing to ponder what could be accomplished when one's already satisfied, and just wanting to push the envelope that much further. Thank you for sharing, and happy listening.
