"my ears have rarely been able to match their test results."

It is important to learn this skill, because the measurements are the sound, with the exception of small nuances. Knowing what measurement effects which part of the sound can really help cut through lots of options and help you "upgrade" you system with much more control and direction.

What is dangerous about measurements is it sets a standard that people can make objective judgements about the performance of equipment, and this is very bad for high end audio. Once you can take your own measurements it becomes very easy to correlate the general performance of a product and what is sounds like. The imperfection of measurements is only human, what we interpret and how we take them.

Information is information, its how you sort it out that makes it useful or not. Whether you hear the information (can't print it out) or see the information

PS: tabulated measuremnts like ".0004% distortion", absolutely useless agreed there. The battery of graphs on Stereophile reviews super useful, even when JA changes the measurement tolerance to make a product look good.
CDWallace – Not sure what you consider “progress”, but I doubt I was leaning towards what you consider progress. After 30 years in this hobby I do still learn a lot, but most certainly not from just anybody.

What I have learned though is that facetiousness and irony is lost on some, and in a big way. Anybody following the thread would know my statement “my ears have rarely been able to match their test results.” is obviously tongue-in-cheek … well almost anybody.

I recall many years back watching a flamenco guitarist tune his guitar with an electronic tuner. I recall thinking that he probably wouldn’t be much of a musician if he couldn’t tune by ear. I was right; he was pathetic.

Same holds for an audiophile. An audiophile who cannot trust his ears is not worth listening to.

Pauly,

I think CDW was refferring to the fact that you made a post that did not directly insult or belittle someone to make your point.

Can you tune a guitar by ear pauly?

Your attempt at humor fell short, as I believe it would be against your nature to place those who measure equal to yourself a true music lover.

But since you are part of the measurmeent brigade! Maybe you can tell us about your speakers and amplifier and how they measure and how that relates to what you actually hear. I would be very interested with what someone with all your experience and knowledge has to share. Sharing some of your 45 years of experience would be appreciated.

What kind of speakers do you have again? Do you use the new ETF or Liberty, Mlssa?

cool
