Anyone ever measure a Sanway professional audio amplifier? Crazy specs...

Lapsus calami - yes, SINAD is Signal to Noise plus Distortion ratio.

Total Harmonic Distortion (THD)

<0.5%from 1 W to full power (Typical value<0.05%)

0.5% is 46 dB SINAD. Enough said?

And I'll bet you still couldn't hear the distortion. SINAD isn't a great specification, and determinant of exactly zero audible concerns, since it conflates distortion and SNR. Issue here might be poor SNR at low power. Depends how quick the amp gets quiet, which you can't tell from a full power SNR spec.

I bet I could.

Yes, maybe you could - if this amp is used as a full spectrum (20 Hz - 20 kHz) amplifier. But for subwoofer duties, at the normal listening distance - I highly doubt you could hear any difference.

No arguing with that.

Take a shot at it. You may be amazed and horrified by how bad your ears actually are...I was. In fairness, there are some who can get into the 50s on distortion in music. I didn't. I'm blaming it on the headphones. https://www.klippel.de/listeningtest/ That some were able to get into the 70s on test tones was surprising. Is it a skill that could be learned? Possibly.
