Right. I read an article I probably can't find anymore by a Hi-Fi tube amp designer bemoaning the fact that there was no objective standard for his product, so the reviews were always a craps shoot.
You can see it in this thread. I'm looking for caps you can't hear, and I'm getting recommendations for caps that sound good.
My point about the Spirit of Music is that even if you could measure its presence, you'd need an uderstanding of it to make the measurement. How could a speaker cable possibly matter? Well, if the interconnect gets over 100mOhms, the damping factor of that nice high performance solid-state amp will be compromised. The dissipation factor of the insulation might also have a measureable effect. And how could the performance of a blocking cap matter with a signal that's 20 kHz max? Well, apparently. a ceramic cap will limit the performace of your circuit to -55dB THD. Again, this effect is measureable.
The problem with studying this stuff and keeping your ears open is that you find that the world is full of bad audio. It doesn't bother regular folk, who might wear tennis shoes or an occasional python boot, but it does cause one to quest after the ever-elusive good sound. It appears unavoidable, but, in a Quixotic way, it's silly to try to maintain -124dB THD+N, when the signal was recorded with a microphone and you're going to play the signal through speakers.
In my case, I'm trying to build a wire using PCM encoders and decoders, bunches of Ethernet cable and a switch. I just want all the good and evil distortion to go away.
Still, it would be nice if I could do it with a dragonburst quilted maple capacitor.
