If I'm going to use a dealer my buying procedure is thus:
1) Identify equipment wanted and find a dealer who stocks it.
2) Phone up or email said dealer and arrange an audition.
3) Listen to said equipment with my own music and if it shows promise arrange a home trial to assess said equipment in my own system (minimum period one week).
4) After trial period is over, decide to buy equipment or not. If I decide to buy equipment I return the demo stock to the dealer and place an order for said equipment and pay, or buy the demo stock (if available) at a reduced price. He might even have some second-hand equipment I like that is fully guaranteed
5) When in possession of said equipment, set it up, press 'play' and enjoy beautiful music
