Thank you for your comments.
This was sort of a test, and, in my opinion, you flunked.
The correct answer is: "Let me first listen to the same recording of this same performance on a system I'm familiar with, and then I will let you know how close your video sounds to the in-the-room sound I am hearing."
Thinking you can judge the sound of an unfamiliar system in an unfamiliar room on the basis of a recording of which you have no idea how it sounds illustrates the foolishness and futility of digital videos of analog playback used in this way.
This particular post recording (which is on tape) subjectively sounds a little bit bright to me. I have a different recording on LP which sounds warm and full and natural, and reminds me of what I hear at Walt Disney Concert Hall.
