Nearly all manufacturers do not advertise/exhibit their product measurements? Why?

If a manufacturer thinks their customers care about measurements, they are more likely to publish meaningful ones. Otherwise, they can do whatever they want. Pretty sure these things are not regulated? Why? Because most listeners could care less about measurements and those that do will conduct their own business appropriately.

Personally, I am a technical guy by profession…an engineer. I am a fan of good quality useful measurements. I create and use them all them all the time to help make informed decisions. It’s not something a lot of people are very good at. Most consumers only care about the most fundamental measurements to determine if a product will work to meet the intended use. The things that determine if a product complies with some common standard, for example. Most have no clue even about that and need someone to help.

My opinion regarding measurements and good sound: Good measurements applied well = good sound faster. It takes some smarts and experience to be able to navigate the world of technical measurements properly. Measurements are a means to an end. The end may or may not measure well, but still might be determined to sound good because that is a subjective determination. I can’t spec out what sounds good to me but I know it when I hear it and measurements probably played some role along the way. Most likely.

My recommendation: avoid extreme positions like measurements don’t matter or if it does not measure well it can’t sound good. Good sound is a subjection determination. Learn to use  measurements wisely if you are inclined to even care about such things. 

Recidivism.

Is this the 3rd or 4th now? So many nasty comments. Is it any wonder why the audiophile community at large is bleeding members?

@mitch2 , the system in your profile looks great, "he shoots, he scores" would apply here, no foul.

Thanks for posting it.

If you listened to 2 amps and liked one better but found out the specs on the one you didn't like were better would it change your decision?

It must not as long as a) you only used your ears and repeated the test a few times to make sure you are right and b) your listening tests were comprehensive enough to cover limitations of the amp.  For example, if you listen at low volumes, the amp may be fine but once you crank it up, it heavily distorts -- something the measurements show you.

Bottom line: listening test are the gold standard.  Just do them right.  That's all.

@amir_asr , I followed your instructions about having a friend switch cables to the letter, I have no idea what you are talking about when you say single trial, you said guess which cable is better 8 out of 10 times, I did that, duh.

Hmmm.  How did this test move from past to present?  Your claim of 100 hour burn-in was before we interacted at all.  Your original story about you liking that cable better said nothing about repeating the test, much less 8 out of 10 times.  You even wondered why I was asking you this.  Now all of a sudden that is what you did???

No worries.  Do you know how to shoot a video on your phone?  If not, get some help and redo the whole test so that we can see and observe.  And *please* watch the video I post on things you need to be careful of to generate reliable results.
