I don't know how the Rhino division of the Warner Music Group selects quad mixes for release on their Quadio series.
It might be interesting (and maybe useful to Rhino) to see a list of quad mixes (that Rhino has current access to) that are highly thought of here on QQ, this type of marketing information seems like it would be difficult to obtain otherwise (there are basically just reviews of the quad mixes in the monthly audio magazines published during the quad era).
