Not sure why people pay $30k for an APx-555. I can measure SINAD up to 128 up to 24v, and 116 SINAD up to 100v up to from 20hz to 100khz. And I have only $5K into my setup. Lots of suckers out there!
All depends on the perspective. One driving a Toyota Corolla doesn't usually call an MBZ owner a sucker, on the auto ownership basis alone anyway, both go from A to B without issues.
