@onhwy61: What you say is true of contemporary Classical recordings, but not of recordings made in the 1950’s and 60’s; all of those were recorded on a 2-track or 3-track machine (that’s all there was back then). Lots of recordings made in England and Europe were done so with minimal miking, including those made with the famous Decca tree, using only a pair of mics.
In the 70's, 80’s, and 90’s there were a number of small audiophile labels (including Wilson) making Classical recordings using only two or three mics, recorded onto a 2-track machine. I have a bunch of them, and they’re not that rare, hard to find, or expensive.
