Umm... I have to admit seeing what I would consider a problem here though. Observation is part of the scientific method, and should not be ridiculed. When members on this site ridicule observation, it is science denial. Indeed, observation is only part of the scientific method, but it is a valid part. Jumping all over someone who all reports his observations, no matter how subjective they may be, does not do a service to anything, or anyone: there would be no science without observation.
Most people purchase audio equipment based on their subjective evaluation. There is no right and wrong when it comes to personal preferences. I suppose there are those who simply compare specs and make their purchases accordingly, and live with the results. Nothing wrong with either approach. As a former engineer, I understand full well the need for objective design criteria and the value of testing and evaluation. As an engineer at Boeing, it could be the difference between life and death, with black and white results. Audio isn't life and death. Competent audio designers can and do design and produce products that test and measure superlatively with fantastic performance, thought, at the end of the day, it's the customer's evaluation, nearly always subjective, that matters most in the marketplace and in the listening room.
