LSA Voyager GAN Amplifier

With my analyzer cheap dummy loads have a -92dB noise floor.
 

Lol! This statement suggests that your analyzer isn't being run properly or its broken. 

What's the saying. The hammer is only as good as the person swinging it? I have already detected quite a few bruised thumbs.

I guess if a tree falls in the forest it really doesn’t make a sound. That is, only if you don’t have the ears to hear it, or the equipment to detect it.

As I noted previously, there isn't much sense to respond to someone without the appropriate experience to comment on a matter (no matter what field, audio or otherwise) - e.g.

Because performance within the audible band is what audiophiles care about. But some folks must only listen to music where all the tones are at 1khz. So this test would be meaningless for them.

1khz is within the audible band. I’m guessing 1 khz is chosen because its harmonics are within a reasonable range. Perhaps a sweet spot. Not sure.

Some people may actually wish to listen to a 1khz tone, but there are probably other meaningful therapeutic influences in play should they wish to do so..

You may wish to listen to a 15khz tone by what you have said. A most interesting anomaly.  I don't think it would be very pleasant.

The point of the 15khz tone is to see if the amp struggles with those frequencies. As most amps have a much harder time as the frequency climbs above 1khz. And there’s meaningful content in music above 1khz.

Most audio specs aren’t to prove how good the gear handles music. They’re simply for marketing purposes. And when the consumer doesn’t understand what actually matters, 1khz is enough to get the job done. ASR is a great example. The quality chart that everyone buys gear based on is all of a 1khz THD+N spec. So Amir's partners (Topping for example), just need to design gear that maximizes that spec (sound quality with music irrelevant), and the commissions come rolling in from the frenzy of sales.
