Here is 'laughably low' distortion for tube amp...see the significant distortion difference from 16 to 2 ohm (bottom to top)

Even low distortion solid state amp behaves similarly. Adcom.

Well, you have to use the amp accordingly to its capabilities. To use a tube amp with a 2 Ohm load on the 8 Ohm tap is deliberately misusing the amplifier. If you do that, you can make all amps look bad, you just have to set the margin 'challenging' enough. I also wrote to avoid 2 Ohm altogether. At 10W and 4 Ohm its distortion is below 0,45%, that is actually still much lower than the most speakers. And don't forget, it's mostly the (often even wanted) K2.

That is actually laughably low distortion compared to the distortion of most speakers, even with the 2 Ohm (ab)use.

That was just an example from stereophile magazine. Even if they would use 2 ohm tap with 2, 4, 8 and 16 oh load, the result would indicate increasing distortion with decreasing load.
But I do not want to argue anymore, I do not care.

Those laughably low distortion amplifiers tent to sound like crap sometimes

I agree. And you can't pair every speaker with every amp. The worst is when ppl just buy the 'test winners' and then realize it doesn't sound as heavenly they thought it would surely do.

It hink you mean, increased distortion with increasing load?
Actually if you decrease the speaker impedance, the amp load increases and not decreases. Or did i miss something?
