I just thought of something that might be good for the short term and long term sales of quad mastering on modern disc formats.
There are Wiki pages for many if not most of the classic titles in the AF 4.0 series. Often the info on these pages does not go into much more than song titles, hits, chart position, producer, and release date.
Sometimes the fanatics will add in information about international releases, alternate cover art, and major reissues especially when a deluxe edition came out, or bonus tracks were added.
I think that going into wiki's pages for the albums that AF has issued quad titles on, and adding several things to these pages could be a benefit to the SACD sales life of the given title. Make the SACD with quad layer a noted and featured release.
For instance, for Full Sail, writing that the album was also mixed into quadrophonic by so an so, and issued "year" on in the SQ format on LP and 8-Track cartridges.
Then further down the page, create a caption Audiophile Releases, or Audiophile Reissues
Under this heading, state the Direct Disc Labs SuperDisc, MFSL gold, and the Audio Fidelity SACD which features the 1974 quad mix. This with more mastering credits and release dates and even catalog numbers. Very detailed and well written into so it does not sound like advertising. Then some links to back up the info given.
This would in fact advertise the fact that the quad mix of each album is now available at retail, and a certain part of the buying public might find out about it only through wiki.
I would be willing to do some of the work to make this happen. I think that doing just the 4.0 titles for starters would not be that big a deal. The results could be surprising.
This would give credit to the mixers, and mastering people, which is the main point publicly. The links added could tell the rest of the story.
