So I consulted my wife last night on the purchase of a new amp.
I’m heavily leaning towards a purifi, most likely the March audio. I was rambling about the impressive SINAD performance and power efficiency over another class a/b that I had been considering. As her background is in audiological science, she mentioned the test batteries involved in hearing aid design, and in particular the use of temporally varying signals as well as/instead of puretone and steady-state broadband noise input for frequency response testing.
I'm a technical layperson so can't really draw any conclusions on this or how it relates to audio amplifier testing in general, but though it was interesting nonetheless.
This article explains some of the standards/practices in hearing aid design:
