Professional recording generally used DBX (I'm told) because it is better. (Pro DBX was not the same as what they marketed to the consumer...more complex). Dolby marketing stategy to the consumer (license the process inexpensively to hardware manufacturers) was better.
As I recall the reason to tape record your LPs was to capture their sound before wear set in. I don't see how this would apply to CDs.
