Everything in the I can ever remember buying usually sounded good enough when I brought it home from a dealer, to know I was happy. Any changes I heard were mostly subtle.
In other words, I knew whether I could keep it or not, at the beginning, or in a few days.
Equipment I've bought without hearing, still gave me an idea what I had to deal with, at the beginning. If it was too questionable, I usually let it go. When I heard that same equipment somewhere else, years later (well broken in), I recognized those same characteristics I didn't like years earlier.
I'm not saying it doesn't need broken in, just be careful if it bothers you that much. A few days should give you a good idea, and time for you (nerves and excitement), and the equipment to settle in. It may not be a keeper, if it still is questionable.
