- Don't audition anything you are not willing to purchase
This is not something I can agree with. Often, I don't know what I am willing to purchase. Often, I need to hear the next level up to make a judgment about what things can sound like. One cannot judge diminishing returns without listening to things at the next level. Plus, many salespeople are more than happy to play things at the next level -- helps educate me, and gives them a carrot to dangle in front of my nose, even if it's down the road.
