@donavabdear. I agree with a lot of what you say about Al Schmitt’s recordings - which are superb. However, I disagree with your "bottleneck" comment. You miss the point that the engineer doesn’t just listen to what’s being recorded via monitors. They listen to the actual sound of the instruments themselves. In addition, good engineers know exactly what every piece of equipment in the recording chain does in terms of the sound which is finally committed to the recording medium. Furthermore, in multitrack recording, the engineer has the opportunity to listen to each track solo and, actually, has access to a lot more information than anyone who only hears the final two track mix.
To conclude, as nonoise says arguments about any piece of equipment in the recording chain setting a limit on what can be used for reproduction are just red herrings.
That’s the end of my contribution on this topic.
