Each of us produces a liter of mucus per day. Snot, actually, and we use it to keep our esophageal system working smoothly. And here's the thing, despite the fact that's a lot of snot, unless there's a problem we never notice it.
And that's the way most systems work, seamlessly and in the background until something goes wrong or we yearn to make something better.
It's the fringes we notice, not the main system.
It is good and proper we focus our time and energy getting our core audio systems functioning properly, but it's almost never what we think about.
I have for many years been a proponent of stepping back from the pieces in my system I interact with like the transport, preamplifier, or streaming interface, and pay homage to my silent partners that make it all happen: the AC power, amplifier, cables, and rack system.
Central systems are easy to ignore until something goes wrong or we wake up to the fact we can make improvements that matter.
