In rereading the article, some LPs were viewed as superior to the SACD.
As for the CD layer on SACD discs, here's a quote from Sony's literature:
Better sound on conventional CD players.
The Super Audio CD is mastered with Direct Stream Digital (DSD) technology. A separate layer, compatible with the Compact Disc Red Book standard, is transferred from DSD using Super Bit Mapping Direct downconversion. The
result is a disc that sounds noticeably better than conventional CDs when played in a conventional CD player. The new disc makes better use of the full 16 bits of resolution that the CD format can deliver.
