I may have been a bit harsh.
It's most definitely rewarding and perhaps even a fundamental skill in electronics understanding power distribution in complex audio systems. Break it down to the smallest unit of processing (a single opamp) and give it the best environment possible to do its thing. You will start viewing opamp datasheets in utilitarian way. Having done the homework I find it somewhat inexcusable to see so many designs skip on this area due to parts count or just applying whatever the first examples of the datasheet does. Although being somewhat absolute on this topic may have something to do with myself having spent so many years in failure mode. In other words listening failing opamps doing all things distortion, oscillation and placebo. This isn't an advanced guru mediation, but comes up undergraduate level in most universities I believe. And way before any serious radio frequency work.
I know there's an actual job out there that blends accounting with EE and JohnRoberts has certainly shared on his experiences on this. I would be curious on why cheap and bad design still gets applied on todays SMD scale. Doesn't seem it would make much difference per single PCB to apply the brute force and perfect approach in quantities above 10000.
