I am surprised by the reactions to the dealer in this thread. I would not have expected the dealer to demo 250 lbs each speakers in my home unless I lived next door, even at $48k. Maybe something that I could take home myself but in reality I have never been to a dealer that was willing to demo speakers at my house. Electronics, yes but never speakers.
I just recently purchased speakers and had no expectation of demoing them in my home. I did take my equipment to the dealer and demo them there. The dealer is 3 hours away and it seemed unreasonable to expect them to deliver and set up the 165 lbs each speakers (which took a full day when they were delivered) on the chance that I would purchase.
Both the dealer and TMR being local to the OP, maybe the dealer knew TMR had a used pair that they were competing with.
