I like that. When you think about it, the audio system and the hearing system are completely different systems; one is metal, fiber and data, the other flesh and consciousness. The former is merely a machine designed and optimized to serve the latter. Any logic that claims the system is a valid entity on it's own separate from the ears is misguided. They are just doing it like a puzzle to achieve low distortion on their oscilliscope for the pleasure of winning the rubiks cube. It never translates into listener pleasure or sales unless the low distortion allows the mind to more easily slip out of sound awareness and into music awareness. We don't hear low distortion. Just like we don't see darkness, or taste water. We hear sounds and we listen to music or stories or whatever feeds the mind.
There is virtue in the technical art of experimenting with different topologies and reducing distortion. That is a lot of fun. But it is a different hobby to music listening. Like engine tuning is different than driving.
To take it a step further, I believe that we only hear the sound as a means to listen to the content of the sound. As long as there is not some gross distortion that distracts the mind from relaxing into pondering the meaning of the content then it will naturally slide into alpha state to become more and more aware of what the music is doing, rather than what it sounds like. Our point of awareness changes from, "that sounds clear," to, "the singer moves me." An emotional connection is made. It has little to do with the gear, except not blocking the emotional flow. High distortion amps like DHT often create intense emotional connection as do paper drivers, oil caps and transformers, all contribute pleasurable distortion. I think music lovers can easily overlook minor distortions because they are very practiced in zoning into the music vibe. But some people are very sensitive to the minor distortions and require more distortion to cover over the objectionable electronic perversions common in value priced gear. Either softer with euphonic distortion, or more expensive to eliminate the distortion and allow more of the edge without the pain. A talented audio designer can achieve extremely low distortion while retaining the musicality at a low price. There are few of these left anymore.
There is a threshold that is different for everybody, where the accuracy and detail of a very low distortion system can stimulate the hearing sense to such a degree that it prevents the awareness from shifting into alpha state, and hold it in active beta state with consequent adrenal stimulation; audio thrills are fun. Over time an addiction to the detail and power can form, and the listening act is only for the pleasure of hearing. It prevents sliding into semi hypnosis and getting into the music. Music is chosen that has no depth, just sonic fireworks, or sounds beautiful. Eventually boredom comes, and empty wallet. Time to rest and back off on the resolution add some distortion. The audio engineer who doesn't understand how the mind perceives music as opposed to sound will not see this, thinking no distortion is acceptable, and they will not produce pleasurable circuits, or make money, except from those who buy into their technical or marketing spin.
I often think about the perception of sound by the brain and the mind. Thanks for starting this thread, Werd.
