I have had quite a few short auditions like that. Often it will be some young kid in an audio store that says listen to this, and the distortion and high frequency noise chases me out in a couple seconds. Usually a low cost system. But I will walk into a demo room with someone auditioning really good speakers like Magico with inappropriate electronics and the same thing.
I am very sensitive to high frequencies distortion and noise. Lots of detail scraping high end and low cost solutions have lots of trash in the sound and I can’t stand them… my partner as well, she has better hearing and we run from the room quickly.
