I find it strange that some spend big-bucks on an amp, only to operate it without any form of maintenance until it sounds suspect.

I guess the example is a pricey vintage car - drive it till you hear strange noises from the engine or brakes, and then get it repaired, or change the oil and filter. At least cars have an odo, and a maintenance log-book, and try to get the owner to keep the car safe and operating efficiently.

There are relatively cheap maintenance processes for checking the health of an amp. With the car example, not everybody has the mechanical/technical nous or equipment to change the oil, check fluid levels, run automated tests, etc. Some amp maintenance processes require electrical competency (eg. to measure idle voltages and currents around the circuit), and some require technical nous (eg. to measure distortions and frequency response).
