... And what of us who listen to our equipment to better hear the music?
Having designed/built my own speakers, I’ve spent years developing the crossovers to attain the sound as close to as I desire from the set of components at hand.
For example, I can spend hours instantaneously A/Bing conjugate capacitors of just a few mfd difference, or even different architecture, to listen for a difference, and if so, which I prefer. And because tracks vary so widely, it takes a lot of tracks to decern if there is an audible difference and which is preferred.
BTW, for those out there that like to tinker, or are just never quite satisfied with the system, by all means build your own speakers and you can spend years tweaking the crossovers at very little cost when compared to swapping out components and/or cables.
