How much can be measured -- and how much cannot?


There has been a lot of discussion over the years on Audiogon regarding the measurement of components and other audio products. Some people claim everything is either measurable now or will one day become measurable with more sophisticated measuring equipment. But others say there are things in high end audio that will never me measurable and that measurements are really not that important.

Here is a typical example -- a quote taken from the Stereophile forum regarding their review of the Playback Designs MPS-5:

"JA 2/17/10 Review Measurements of Playback Designs MPS-5
Posted: April 13, 2011 - 8:42am

John Atkinson's 2/17/10 review measurements of the Playback Designs MPS-5 revealed less than stellar technical performance even though Michael Fremer really liked the player. I've included JA's closing measurement remarks below followed by the manufacturer's comments.

To my knowledge there was never any followup in Stereophile regarding the manufacturers reply the MPS-5 could not be adequately measured with traditional measurement techniques.

I believe Stereophile should respond to this reply in the interests of its own measurements credibility.

How important do you think measurements are? Are the ears really the only true arbiter?

To me the best speakers give me an emotional connection to the music. The final of the Sibelius 2nd will give me goose bumps on certain speakers. I know of no measurement that will tell me which speaker will do that for me. Remember early solid state and early digital cd players measured great but sounded terrible. The statement above that measurements alone will tell you if you will like a certain speaker is just nonsense
"The final of the Sibelius 2nd will give me goose bumps on certain speakers. I know of no measurement that will tell me which speaker will do that for me."

No, but to Almargs point, when shopping for gear with the best chance of doing it, impedance specs allow matching from output to input that if accurate and applied properly as a factor in the decision making process is more likely to result in better dynamics and lower distortion, two attributes that are generally desirable from a goosebumps perspective regardless of what speaker is used.
In reply to Charles1dad, good sound is a comparative thing. If you don't know bad sound it might be hard to recognize good and nearly impossible to fully understand great sound.

Your attribution of beauty and enjoyment to components is exactly the type of marketing conditioning I was talking about. Over time each of us has developed a belief system about sound and music that largely predetermine our opinions on certain audio subjects. This is not necessarily a bad thing, but once you take it into account questions of measurements vs. subjectivity become largely irrelevant. We can trade opinions, but our belief systems, which I believe are marketing driven, prevent us from being educated, at least to some large extent.
Onhwy61,
I honestly don`t get your point. When I attend concerts it`s for the pure joy and involvement that music provides. With my home audio I attempt to come as close as I reasonably can and with my current system I`m extremely pleased with it. It`s that simple and straight forward for me.We just have different approaches and apparently different objectives.What ever works for you is the way to proceed.

Marketing has nothing to do with my choices, only the end result which is the sound and my response to it(it moves me or it does`nt).
I appreciate your different perspective.
Regards,
No, marketing is not driving what I think sounds good. I may be enticed to purchase a product, but after it is in my listening room the marketing is all over and forgotten. If it sounds good to me, I keep it. If not, I sell it or send it back.

Markering influences the buy decision, but never the keep and enjoy decision. Marketing's influence is very short lived in the end.
