You're probably correct. That means the audio CD offered cheaper manufacture and superior sound. (Vinyl lovers will dispute the superior sound claims.)
Call CD sound "more accurate". Vinyl lovers historically loved vinyl precisely because they love the particular inaccuracy it imparts. CDs are more accurate. Brutally so at times, even. Especially when they're being really, really accurate at conveying clipping brought on by the loudness wars.
(Now I suspect vinyl's main purpose in life is as a marker of being a discriminating consumer who doesn't want to be a victim of the loudness war, since you can't overdrive a vinyl record in the same way for physical reasons. It is unfortunate that one must go to such measures to opt out of "music that sounds like crap because you ruined it, you stupid music companies".)
