I have several pairs including JBL 305p mkII. Also, headphones like AKG K701.What speakers do you have, and what is their level of THD at say 95 db?

Assuming they are as good as the 305 mk 1(they might be better) they are close. Here is a 305 playing 95 db at 1 meter from the speaker in 34 ft x 19.5 ft x10 ft room. Which is really too large for them. It bounces around .4% to just over 1% mostly at 300 hz and above.I have several pairs including JBL 305p mkII. Also, headphones like AKG K701.
I don't listen that loud but you're right.Assuming they are as good as the 305 mk 1(they might be better) they are close.

Absolutely. I in no way endorse amps having distortion more than is design-practical at a given price point. 0.1% seems to be about the most anyone ought to accept in a solid state electrical circuit. Besides, one's loudspeakers (and other analog sources if you use them) will provide enough distortion to satisfy.The problem is that music signals can vary so much, so being on the safe side is just a good thing.
Very impressive, did you try the Chapman track?I managed to get a perfect score using STAX SR-001 Mk2 IEMs and an RME ADI-2 DAC as a source.
I found that some of the "lower" distortion tests were easier to decipher than some "higher" distortion tests. Very strange.
I think this is a great ear trainer nonetheless!

Ran into this interesting listening test by Klippel with regards to how much distortion you can hear.
This is the link: http://www.klippel.de/listeningtest/lt/
I didn't bother with the music tests, as they aren't as linear as the sine wave tests. There would be no way to get an "accurate" self measurement IMO.
- I love Tracy Chapman's music and found her recording to be decent back then, but I don't understand how it can be used as reference these days. In a way, it is the Lenna (https://en.wikipedia.org/wiki/Lenna ) of audio. I can see someone publishing a paper about TC's recording as being among the best in the early 90ies, others quoting that paper and using is as a standard, but I just find it OKish these days.
