Join an audio club, if there is one in your area. Go to meetings. Make friends with the other members and ask about reciprocal listening sessions. If there isn’t a club in your area, start one. Or, as @simao suggests, check the location of fellow audiophiles on this or other forums and make friends that way.
Since becoming active in the Portland (OR) Audio Club, I've heard many systems, with a wide variety of gear and setups I wouldn't have heard otherwise.
