No, the story that emerges is that no toob amp, irrespective of cost, can be as clean as a good SS amp even at mW power level (as if that has any relevance anyway in the real world).
It still has very low distortion , how much distortion is too much ..?

Well, if you do know, what was this upward distortion curve graph supposed to show?

Yes he does, so? How is that relevant to distortion vs power?

You mean the hard clipping? How about not clipping the amp?

The argument was about SS vs toob distortion at low power and which has it lower, not about how much distortion is too much.

But it ain't lower than SS so basically you had no point the whole time.
How the amps clip is irrelevant to how linear they are within their power limit. And I'd prefer the clipping to be as noticeable as possible so I can avoid it.

for the 50Hz: 1st Benchmark AHB2, 2nd Boulder 2150, 3rd Audionet Max
for the 1kHz: 1st Benchmark AHB2, 2nd Audionet Max, 3rd Musical Fidelity AMS100
No links there. The reason is our ears are tuned to birdsong frequencies (Fletcher-Munson). It matters what distortion harmonics are turning up in that range; that's a range that if enhanced, will be described as 'bright'.

Now you're blaming the measurement and the power chord?
Was I not clear about that?

Yes, if and when the distortion raises above the noise. If not, you'll just have a straight downward curve right until clipping. Any amplifier, tube or SS, SE or PP, has less distortion at low power than at high power.
You do realize a problem here, right? Why would noise increase at lower powers? Noise is in any amp I'm aware of, a constant.

Are you seriously asking this question? For real?

Sounds like an impasse to me.
Put another way, noise is a constant and does not increase at lower power levels, but distortion commonly does. Spend some time with an amplifier, a sine oscillator and a few amplifiers and you will see what I mean.
