I Am Tired of Bogus Measurements

Also, I don't buy the parts tolerance argument. I'm a retired bench technician (Component level) and most audiophile grade equipment tolerances are very tight with many components within 1%, They are much more consistent than that especially when new!

I can't speak for audiophile speakers, but for professional speakers, most of our parts are +/- 3%, some +/- 5%, some were specified tighter, and some were specified looser.  A good designer/company will do a sensitivity analysis as part of their design and design validation. The architecture affects that sensitivity. A low order crossover will be more tolerant of component variation than a higher order crossover.

If I was designing for the potential use of tube amplifiers, I would improve some tolerances to improve impedance consistency.

You argue too much.

Is that a response to asking for your comments on the full AES article you linked to (that is behind a firewall)?   I find a topic called, "I Am Tired of Bogus Measurements" without substantiating that measurements are bogus as argumentative, but is not the whole point of being here to discuss?

What proof do you have?

No need, just buy one and some speakers then post it in your system with some pics.

This is what I said in the OP:

The cancelling of brands, the talking down to the customers, is bogus.

If you want to at least appear credible post your system and in room FR measurements.

Interesting article on measuring speaker cables, are high priced cables bogus, or not? The bogus websites deny, deny, deny that cables matter, offer them proof and they deny, deny, deny the very "measurements" they claim to embrace.

ABSTRACT

This paper describes a simple experiment to identify the performance of a number of different speaker cables by measuring the “error” introduced into an audio system by each cable, i.e., the voltage drop between the amplifier and the speaker. The signals used are both white noise (https://en.wikipedia.org/wiki/White_noise) and music.

The results show that the principal factor determining the error of a cable is its geometry. Cables with very widely spaced conductors have the greatest error, closer-spaced conductor cables have less error, and very closely-spaced, flat conductor cables have the least, or near zero error. [Townshend Audio’s Isolda speaker cable is such a design. – Ed.] The results have been presented both visually and sonically at https://youtu.be/v11hmOE1Vcc.

The experimental method has been described in detail, to enable researchers to repeat the tests in order to verify the conclusions. The results of this experiment may embarrass those cable sound deniers who have hindered the advance of hi-fi for the past 50 years, and hence may allow the quality of high-fidelity sound reproduction to advance.

How can a measurement, unless it is inaccurate, "cancel a brand"  ?  Can you point out some very specific examples of this and how the measurement was inaccurate and cancelled a brand?

"Talking down to customers" ?  Do you have a specific person in mind and example? Specifics matter. If you mean the general tone at Audio Science Review  to those that don't believe the same thing without stating it, I would not totally disagree, it can be toxic, but I would hope you can then also agree that the treatment is no different here to people that disagree, it is equally toxic.

What proof do you have?

What, do you think I am going to post bills of material?  How about doing some research on audiophile speaker component tolerances and comes back to us with your report. +/-5% total tolerance on a film capacitor for audio is pretty standard, but depending on the vendor, 95% or more of their distribution is +/- 3% or less. It comes down to who is going to pay for screening. Air core inductors are typically much better than +/- 3%.  Even cheap iron core inductors are +/-3%.  High tolerance high wattage resistors are surprisingly expensive, so you ensure your designs are more tolerant of variation. Fortunately, where resistors are used, that is often the case.
