Its a serious question. Totally get where you're coming from. But at the same time its equally obvious there's no answering. It might seem obvious Alvin and the Chipmunks recordings, or maybe the Monkees, are pure commercial with no audio quality aims whatsoever. Except the minute anyone says that starts the inter web clock ticking and its only a matter of time before some know-it-all points out the Monkees were recorded by Sam Ricker and mastered by Doug Sax at the Mastering Lab. Who also did the speed warble for the Chipmunks.
Did you know by the way Kind of Blue was taped on one machine and mastered on another with a capstan change that resulted in this audiophile classic being sold in the millions at the wrong speed? So even when great care is taken.....
