I just received my M22Ti, and used a Nakamichi receiver to drive it. Unfortunately, the first sound was so "tight" (the sound stage was even worse than my 10-year old $90 Yamaha speaker). As I know, most of new speakers require some period of time to break in. I do believe that M22Ti should perform much better than the Yamaha speaker. But how long does it take for M22Ti to break-in? Is that the reason for the "tight" sound or does the problem come from my receiver?
