In the past when I had a local dealer anything that was demo or used, I was able to do like others have mentioned to take home over the weekend. I would never of expected to take a new product home out of the box because then they can’t get retail for it anymore
it sounds like this dealer is letting you demo a new piece of equipment so he’s going to take a hit if you don’t like it
one of my strategies is to shop the online market from places like Crutchfield, and upscale audio and look for a demo unit because they’ve already discounted it from being new that way if you return it they don’t lose anything
