a) Network/Socialize/Make friends with local audiophile in your area.
b) Audit gear in their houses, let them audit your gear/room (catch flaws with your setup, etc).
c) Start a gear loan program with such dudes. You loan him something for audit, he loans you something for audit. If he really likes what you have and you really like what he has, it may convert from loan to trade, etc.
Note:
If dude lives in a 1 horse town, he may be out of luck (w.r.t a through c). If he is very antisocial and introverted (a percentage of audiophiliacs), a through c may not quite work for him either.
