Home demos are such a conundrum. The speaker/room influence interaction is so dramatic that no two rooms sound the same so the speakers will sound different in each of those rooms. I like @sounds_real_audio idea of a dealer visit. It is true a way to listen at home is an important feature of purchasing hi end home gear. It's easy with everything but speakers and turntables that require set up and space. In our pro business, when we do a demo for a studio, we go set it up for the customer- the dealer doesn't do the demo. The results for everyone is much better this way, IF we did that in hi fi would possible buyers be more comfortable if the company itself set up the demo or the dealer?
