What's relevant is how the high frequency hash affects the downstream electronics -just like the test instruments.JA frequently comments on the amount of noise switchers generate.
"Because the Stellar M1200 features a class-D output stage, all the measurements other than the frequency response tests and one of the squarewave tests were taken with Audio Precision's AUX-0025 auxiliary passive low-pass filter, which eliminates much of the ultrasonic noise that might otherwise drive the analyzer's input into slew-rate limiting. Without the filter, 373mV of ultrasonic noise was present at the amplifier output terminals."Nearly half a volt of garbage!
