Good post.
"and it could be argued that HDR improperly implemented can result in a look that is more jarring and irritating than ever before even if it is more accurate up to a point."
Why is a car radio rarely irritating, but a stereo often is? Objectively the sound quality of a regular car stereo is much worse than that of a good home stereo, and it usually has clear limitations in the frequency extremes. But perhaps it "fails gracefully", to use your term, while a home stereo often fails in a, to again use your words, jarring and irritating way, even though its failings are objectively less.
It takes a lot of work to have a home stereo fail gracefully, but in a good way -- by solving problems, such as are individual emphases and accents, not by masking them.
Al, These are some good observations. Thank you. To me, a car radio is rarely irritating because it makes sins of omission. Frequency extremes are compromised. Modern music is compressed to overcome the ambient noise in a car. Older music, particularly dynamic classical music, is very difficult to hear in the car, but this is not because of the car radio, it is because of the noise one hears while driving. Listening while not driving can be very satisfying because of lower expectations.
Home stereos, by contrast, often commit sins of commission, and with them come much higher expectations. Frequency extremes at home also often have clear limitations, but not because they are absent, but because they sound so fake. They are jarring and irritating, both in the treble and the bass. One could argue that these failings are objectively less, but I am not so sure. I think they are certainly subjectively more, precisely because of the expectations.
I do not think car radio fails gracefully. It succeeds quite well at achieving its goals, IMO. Expectations are lower, so success is easier to achieve. Expectations for owners of high end audio systems are much higher. At times they fail, and not even graciously, to meet those expectations, so they are sold and something new is tried. And so it begins again.
I agree with your comment about the importance of solving problems inherent in our efforts to reproduce music at home. It is much better to solve the problems than it is to mask over them. Wires were introduced that masked over hot drivers for instance. But once those drivers are abandoned, then what happens to those wires? Big, heavy, powerful amps are designed to solve the problem of driving inefficient speakers, but what if drivers were not so limited? It seems to me that new problems are often created when trying to solve other ones.
The contention arises from the notion that some listeners think most of the major problems were solved long ago, and so we have vintage systems like mine and others. Yet other listeners think new is usually better and surely gets them even closer to the absolute sound. Perfect sound introduced in the '80s was soon thereafter "solved" by introducing lots of masking of emphasis and accents, smoothing, and covering over. But later more enhancements in speakers and electronics and cables were introduced to bring more "detail" and alternatives to different absolute sounds. More recently, digital failings were discovered and addressed, some think solved, while even newer problems with, for instance, streaming are introduced. So new interfaces, new advancements, and so it goes.
Yes, It does take a lot of work, often an extreme amount of effort, to select and set up a system that presents believable or convincing music in the listening room. I do not think we should aim to fail gracefully. We should aim to succeed with a system of components that bring us as close to a natural sound and the music as possible, while knowing there is a reference and a goal.
