I'm torn here. I'm going to listen to a pair of speakers and don't know how I want to go about this. The way I see it there are two choices, each have their benifits.
1. Listen mostly to somewhat unknown music presented by the guy who owns the system. He knows what shows off the attributes of the speakers.
2. Listen mostly to music I am familiar with. This will show me a comparison between what I have and what he has. Of course the down side is that different music sounds best on different systems.
