"Disagreeing and being adamant about using some sort of random musical waveform for measurement and calibration is absurd. Do you have any background in electronics to understand what it is you that are proposing?"
My personal background is in music, not electronics. My opinion is that the testing regimen for electronics is inadequate, that is all. I don't consider musical waveforms to be random, and that it should be possible to take a minute or two sample of music and test using that, as opposed to a sine wave. I am suggesting that the state of technology for testing electronics is inadequate, and consequently one must ultimately trust one's own ears. I am disagreeing with the notion that testing with sine waves provides an objective evaluation of audio quality. Perhaps I am incorrect, but I am not at all confused.
I think it is a good concept, that may happen some time in the future as some sort of supplemental tests. As it is now, testing with sine wave, and noise, usually (there are obviously exceptions, that's why there are other tests) would represent more severe tests than using music tracks. For example, you can use a music track that has very high dynamic peaks, but it is still normal enjoyable music, the high peaks will be of very short duration such that even if it results in the output voltage clipped, it would not likely result in an audible issue. If you want to make sure there is no potential of audible issues, then you can simply allow enough headroom, and that's one reason why test benches often use 2 V for pre outs if unbalanced, or 4 V, if balanced when in real world home audio systems, most people can do well with just 1 V or less. On the opposite side, if using sinewave is too severe a test that does not represent real world issues, that's better using some music tracks that while it may make the test results look good, it may not provide a good comfort level for a lot of people who want to have more than enough safe margins, to allow for the worse use case scenarios.
If the kind of music tracks you might have in mind are used, the selection of such tracks would likely be controversial to begin with, and the testing protocols would have to be developed. The developmental work and the ultimate testing protocols will naturally be much more complicated, due to the very different nature, one being that the contents will be so time variant in nature. As it is now, it is tough enough for the readers to find the standards and protocols reviewers are currently using, in order to compare all test results on apples to apples basis, imagine how much more complicated/convoluted it is going to be if sine waves and noises are swapped with preselected music tracks. In theory, anything can be done, but in my opinion, what ASR's current testing are closed to being adequate, it would be much easier to fine tune, or supplementing what's being done now, than to complicate things further by using music tracks that will bring about a whole new bunch of issues to deal with.
