What are some good things to do when going to an audition

@tee_dee ,

20% is not out of the ballpark at all and even more sometimes. I would start with something like 30% and get down to an agreement from there. Why would audio equipment be different from buying a car, house or anything else? They don’t think it’s rude happens everyday for them. They want to make the sale. It’s all a game.  They want to get the most for what they are selling and you want the most for your buck. I buy expensive things for a living so maybe I’m jaded. 
 

When going to an audition a good thing to do is to listen to music 

Familiarize yourself with a particular song track you enjoy, and how it sounds.  

Take notes while listening to the same track on different systems, speakers.

You can start by simply noting likes and dislikes for each system you audition.

Show up stoned wearing sponge bob boxers. Have been known to immediately suggest in home audition....

"I always operated assuming the price tag is the price I pay."

If you're ready to buy, it's silly not to ask if they can do better, especially if it's a demo model or a trade-in.   They usually will find a way to make the sale if they know you're about to buy.
