Hello again.


i saw few pro amps show only this specs:
THD+N in % at 1 kHz

consummer add this spec often:
THD+N in % at 20 kHz (100 W into 8 1)


Both of consummer and pro amps, if i turn down the volume it will lower THD+n by a good to hudge ammount.

Maximum average power in watts at 0.5% THD, 1 kHz for a class D amp of my choice:

2 ohm 1,200 watts
4 ohm 775 watts
8 ohm 440 watts

If i lower volume to 80 -95% it should be fine no ?



This time reading about harmonic distorsion.
I discovered:
Human hear is the most sensitive at: 2,000-5,000 Hz

So if i understand less than 1% of thd+n (100 W into 8 1)
if a distorsion happen between 2000-5000 hz

I will dislike the sound.

1% distorsion outside the human hearing range is nothing, right ?

By the way i found something irittating:
Shops i visited when they put integrated amps specs,
They put the préamp specs like if it was the amplifier part.
It's confusing, it force you to visit the brand website to find infos.
