What's The Furthest/Longest You Have/Will Travel To Audition?

I have few options for auditioning a decent variety of equipment (speakers and amps), in my neck of the woods.

I'm considering the rationality of flying to another state to visit a large reseller of brands I would consider
purchasing together.  Otherwise, I would have to purchase components individually without being heard together - could be an expensive mistake.

So, how far would you go (driving or flying), assuming the travel cost wasn't prohibitive?
