I can’t tell you how many terrible sounding concerts I have been to.
I stopped going to amplified concerts over twenty years ago. I had to put paper in my ears to prevent hearing damage. I still had access through conferences I attended every year… I would stuff napkins in my ear… seldom have i lasted more than one or two tunes.
I have been to the Orange County Conference center, Orlando at least a dozen times. It sounded pretty good once.
Generally too loud, difficult acoustics, electronics built more for volume versus quality, In house audio engineer… well, I don’t know what is wrong with them. I am sure one could come up with a half dozen more.
Even twenty five years ago my system sounded much better than I could hear at a concert. Also, I hate fighting to claim seats.
However, I have had season tickets to the symphony for over ten years. Reserved seats on the aisle, front and center. From my seat if a violin soloist is playing a Stradivarius it takes me a couple notes to be able to tell. The sound hole of the violin is pointed at my seat. This also helped me calibrate my hearing for choosing electronics. Has been one of the most positive influences in audio for me.
