Yes, this has come up before although going from memory it did not have a dedicated thread. I could be wrong.
An interesting test probably posted before although it didn't come up in a search.
Also try difference sources ie ear phones vs speakers.
5% for the music, 0.5% for the 500Hz sine and 1.5% for the 100Hz sine. A dual tone test such as the one available on Klippel's website also produces rather interesting results. My threshold for the Klippel 70/800Hz test was -65dB.
What do you know, slap bang in the middle of the bell curve:5% for the music, 0.5% for the 500Hz sine and 1.5% for the 100Hz sine. A dual tone test such as the one available on Klippel's website also produces rather interesting results. My threshold for the Klippel 70/800Hz test was -65dB.
So don't chuck out my hi-fi and buy a Bose bluetooth speaker just yet then.On the other hand, when your speaker has 1% distortion in the bass at normal listening levels (mainly 2nd harm) there is still a case for an amp being well below that level, certainly when harmonics are higher order.
Take for instance crossover distortion from poorly biased class AB amp.
measure distortion at near full power and SINAD will look good.
Listen to the amp at softer listening levels and you can hear not so pleasant distortion while the SINAD number may look good.

Seriously, crossover distortion has been a non-issue for half a century or more. It was identified, solved and discussed until the cows came home. The fact that silly old Benchmark dredge it up, misrepresent the severity of it, and claim to have miraculously solved it (yet again) is hilarious. Don't make the same mistake as they do. Please.
Show me several, decent, integrated/power amplifers form any major manufacturers in the last 50 years with crossover distortion problems. Seriously, I bet you cannot.
It's a dead-horse in 2022 and you know it.
I don't know and I don't care! It is a complicated question because there are too many variables but I'm pretty sure I can't hear 1% THD and if I was buying an amplifier I wouldn't bother comparing distortion specs.How much distortion can you hear?
@DamianW, I have a thread for Klippel at:
