I Am Tired of Bogus Measurements

My expensive shoes have measurements but it doesn’t matter, all I want to know is will they fit. My expensive new suit has measurements but it doesn’t matter, all I want to know is will my expensive new shoes match.

The people being misled by measruements aren’t being led my manufacturers, they are being misled by reviewers. Idiotic rankings of digital gear based on measurements outside the range of human hearing. Cancelling entire brands who put out features customers actually want as they sell to humans, not bats. The worst of these websites will rant about their own superior $$$ equipment but mot even one person will ever use speakers in a klippel matchine, they actually put them in a room! The horror. The cancelling of brands, the talking down to the customers, is bogus.

You need to measure what matters! Are the customers actually happy? Is the warranty honored? Most importantly is their an in home audition period?
I don’t need someone to tell me if I could or should like a product. My room is not a test bench, or a klippel machine. Who cares what the component measures by itself because unless its a clock radio I’ll never use it by itself, I have to interconnect it in a "system" with "high quality" cables, (as in all cables are not the same).

If you want to measure something measure how your personal system of curated components interact with your room. That’s it. The rest of the stuff you could forget because these days if a brand overpromises and under delivers they will be following a formula for losing money, an no company likes that.

Here is a study done by Nordost that I replicated in my own system and the reduction in noise is obvious. In this case I bought an after market power cord, a vibration control device, and a QRT power conditioner AFTER an in home audition. If it didn't sound right I could care less about the measurements, in this case the measurements actually confirmed what I was hearing (table on page 4).

So are after market power cords, vibration control devices and power conditioners bogus if they measure well and make the system sound better? Does it win a prize instead?

@kota1 these guys are talking about measurements to level match before you A/B speaker cables of the same Gauge, which doesn't make sense if there is no difference in cables as they claim,  how would it be louder with one cable than another if as they say no difference than no level match should be needed.

That paper is brutal.

1x CD player, older, $4000 ---  I have an idea, how about tell us the model. Why is that a secret?   It was obviously a unit with troubles that conveniently measured poorly. I am making a leap there? You bet, but I have a reason. That reason?  A current, $250 Japanese CD player was better than their $4000 unit, quite a bit from the pictures shown. They needed to pick something really awful to show a difference. They gamed the test. Worse, they gamed it in another way I will mention later.

29 graphs, count them, 29, not one of them with an adequate scale being used, let alone always with a good description and most of them, with absolutely no scale at all.

They have some pretty big claims of timing errors, 20-40useconds, though how someone could replicate this with almost no data I have no idea. Of course, they are using what could be an ancient (and purposely chosen) CD player, and to make it as bad as possible, they are using a CD made on a computer CD writer, not even a pressed CD. At this point now very old CD player, well worn, and a computer made CD, with "sample sized", their words, timing errors. It sounds like the CD was misreading. I could see a mechanical platform improving that. Personally not played a CD in over a decade. Rip everything to storage.

All papers are brutal, I cited that one as an example. I did an in home audition using their method, it worked! Go figure.

Not all papers are brutal. Some are good, some are average, some are questionable, and some are really brutal. Both gaming the results with a really awful, but hidden source device, and a ton of graphs without scales, no pictures of the setup, limited details on the processing other than trust us, etc.  It is particularly bad.
