@larryi I like the idea of comparative listening (between old system and audition) using a near-field listening approach. I think it is a good way to take out a lot of the room and is now one of many tools I will use if I ever need to audition again.
I think there is a bit of a sliding curve on what to expect out of a dealer that relates to the gear you're looking at. I'd not expect the 'white glove' treatment for inexpensive items when compared to real high-end auditions of good gear.
Same thing goes for pricing. The less expensive the gear the less to work with so I'd not expect 25% off $2000 speakers. But, some gear, as great as it is, is very expensive. There appears to be a more room to 'adjust' at $25k, etc, and up.
