Marburg, editing a recording to remove a mistake doesn't seem to me to be the same thing, or done for the same purpose, as an enhancement "through technology to the the point where it is no longer a close equivalent to a real instrument".
For example, Glenn Gould spliced tape to get the most perfect expression (in his view) of the music as it was written. I believe him to have been a bit compulsive about this but I'm not arguing with the results.
The goal of high end playback technology is similar in nature although the expression is not the same in kind. What playback wants to do is alter the original recorded signal as little as possible.
That has to be done with a grain of salt when we are remastering Alan Lomax's recordings of Jelly Roll Morton, for example, since the recording technology produced a signal with speed variations.
I guess this is where your point seems relevant to me. We can all agree that a musical sound is more natural when the recording and playback systems don't change the data or introduce artifacts. Some of us can hear the imposed data better than others, but all of us can hear some things.
