Well I'm not sure what the supposed benefits would be wrt sound quality. I can't imagine there being any if the disc burns properly, my original interest in CDs would have been for archical properties for storing photographs and other data. Kodak Gold for a long time had been one of the better formulas, maxwell might have bought it though.

Burning at a lower rate should in theory ensure fewer errors in the burn but I always wondered what that mattered if the disc check came up ok.
