I had in mind putting together a relatively simple amplifier circuit and comparing a few different op-amps with the APx555. That way you don't have a DAC or a power amplifier to mask the distortion and noise of the op-amp.I have done a number of those as well with no difference seen. I did it for Topping DAC and at least once for Hypex based power amp builds.
More useful for those of us who like to design our own equipment, so I understand if it's too niche for ASR to bother with.
