I don’t now why there should be such an insistence put on tests, charts and measurements when expressing an opinion about audio equipment on Audiogon. This website is comprised mainly of hobbyist who can listen seriously and verbally communicate what they hear, as a means of discourse with others who are doing the same. Sure, there are likely plenty of members who understand the science behind what ASR is doing (but may still disagree with their conclusions). But there are members who are more like myself. Those who have studied harmony, counterpoint, orchestration, arranging, conducting and music history to a certain degree. Who grew up playing an instrument and joined a band in their adolescence. Who attend concerts and recitals whenever possible. These types of personal life experiences are why I comprehend a listening review more than the triangulating of frequencies and mathematical charts. I’ve built sound waves and used charts to incorporate percussion rate, fall rate, attack rate, etc.. before interfacing them with an electronic polyphonic keyboard, so I know a little but my listening preferences are primarily based on what I hear, or what someone else describes hearing.
My father used to build cars before he got a job building aircraft engines. He can explain every part in a car and evaluate whether or not there’s a better or more economical way of engineering it. Today, people like him are usually involved in research. But despite his knowledge, he has terrible taste in cars and I don’t need to know what he knows to choose a better car than he would. Also, he’s always been a pretty bad driver. This of course may not be the best analogy but I’ve personally developed a way of evaluating based on listening reviews relevant to both equipment and recordings. And regardless of what I find in online publications, the best way for me to audition audio equipment is to actually hear it. I’d make the radical assumption that most people who are involved in this hobby can make sound purchasing decisions based on listening evaluations.
