The Point of diminishing returns an interesting discussion

[6.5CM]

The test above isnt simply sound, but of distortion. I am not an expert on distortion. Even though I've worked on pro-audio, Ive never worked with a distortion generator to actually have experience with one.

Cursory research tells me the information provided is incomplete.

To hear distortion, it must be over a threshold. % is insufficient. It will be more helpful to know how many db's the distortion is over the signal, per this paper - https://benchmarkmedia.com/blogs/ap...preting-thd-measurements-think-db-not-percent

This article says that audible distortion threshold also differs depending on the frequency its on - https://www.axiomaudio.com/blog/distortion

Stepping back a little bit, the premise was - "Unlike our taste buds auditory memory is virtually nil."

I am not sure how a 2.5% distortion test addresses that. I seem to have been taken on a different tangent here.

The AES test states "The results are generally consistent with threshold estimates from psychoacoustic literature, that is, listeners often fail to prove they can hear a difference after non-controlled listening suggested that there was one. However, the fantasy of audible differences continues despite the fact of audibility thresholds."

If you cant tell audible differences between speakers, then they all the same. I disagree. I call BS.

The point of the distortion test was that only the rapid ABX group had significant results, and had significant results even with an undisclosed lower amount of distortion. That same group in a subsequent long-tail test did not have significant results. The other group didn't do a rapid test and didn't have significant results in either test. You may want to read it again, as your initial response doesn't align with what the text stated.

All the Benchmark article is saying is that it's easier to interpret dB rather than percentages. They even tell you how to convert the number: 2.5% THD is -32dB.

"If you cant tell audible differences between speakers, then they all the same." is affirming the consequent. This is about thresholds and resolution of echoic memory. It was never stated that no differences could be remembered.
