This article is probably one of the last times the words "Quad", "Quadraphonic"
were mentioned in print, just 2 months before, the SSI 360 Dolby Surround
decoder was tested (by High Fidelity) and, IIRC, Dolby Labs allowed the
"Dolby Surround" logo to be used on Home Videos starting in ~1986.

The Quadraphonic flag in the subcodes was present since the redbook cd specs but it has never implemented anywhere; IIRC in order to store 4 channel in the digital space of two channels at 44.100 16 bit the sampling rate was down to 32000 and bit was 12 (or 13). Remember that phisical spinning of the cd was 1x speed and there was nowhere in sight the faster ones that become common many years later.
 
ugh what a dreadfully negative view of just the kind of Quad music i like; unusual mixing techniques used on close-miked, multitracked recordings. blah!

..and when i see the "G"-word ("GIMMICK") used in relation to that style of Quad, well that's the red rag right there. i read to the end but that paragraph killed it for me 🤬

At the 1981 SCES in Chicago, I picked up a CD system brochure
published by Philips.

IIRC, there were a couple of sentences about the Quadraphonic
capabilities of the CD (4 16 bit/44.1kHz channels) with 1/2
the playing time of the Stereo CD.

(I'm looking for the brochure, I'll scan that page if I find it)

IMHO, the article seems to favor the Classical Music type of
Quad recording (LB and RB for mostly ambience), it seems
to me that most popular music is gimmick-laden (by the
article definition), be it Mono, Stereo, Quad, Atmos, etc.

It took another (about) 12 years to get Surround Sound on
a CD size optical disc (DD and DTS on DVDs).
