. I'm sure it will be written off as just warmth or euphonic distortion - but in the Meishu's case higher resolution would be more apt - now where's that darm resoultion sounding more like music graph. Since someone going in and listening to them would not know since the amp is coverred and looks like a big SS amp and since the company doesn't advertise or produce any product literature and the stuff is relatively ugly - people are buying on sound alone
Sound alone? In this cases of evaluation at a dealer, their is no way to distinguish what is really a different sound vs. a psychologically induced difference. Let's say you compared amps E and F on speakers A at dealer Z's store. How did your dealer level match(human hearing is not linear vs. amplitude difference) the two amps? How is he switching them without you knowing? If you know, then you can not rule out psychological induced factors. Name, look, dealer's tone of vioce, etc. will have effect on your perception.
