I’ve found the best way to show my system off to others is to let them control the queue. While the listener may appreciate analyzing the music you play, they will likely not resonate emotionally with it because they don’t know it very well.
That said, I do have a number of test tracks I use for myself to evaluate performance for customers when they visit, which I also use for myself when I am swapping or repositioning anything in my system.
The list below is just a few of what I would recommend to others.
