Hey,
Sorry to mention...
But this tread is about Zappulse.
Could you people relax a little bit...?!?
Cheers Jan Jensen

Sorry!!!
You are complete correct, I didn't look correct. It comes from the 700XE this looks so similar to our 700......
My deepest apologize.......

My opinion is that if you can lower the THD by removing the 'problems' and unlinearities in the signal chain, then it's a good thing.
If you can only do it by adding more feedback, then it's a bad thing, even if you end up getting better THD specs.

Hi Lars Clausen,
Then its useless to say that Lower THD figures has something to tell about sound quality..If yes, then why are most people go for lowering the THD to improve sound or they simply want to improve something else...lets say the specs sheet or a product datasheet...figures...
please do reply....
thanks,

Kanwar: Thank You for this question. I think it's a very good question!
I think the explanation to this seemingly irrational situation is that if you look at it one dimensionally - like better / worse sound - then you are right, it doesnt make any sense.
But i think you have to look at it with more variables. An amplifier can have better resolution, dynamics, clarity, soundstage etc.
Resolution and clarity are both related to low THD. But dynamics and soundstage are more related to feedback topology and factor.
So if you can get better resolution and clarity without sacrificing soundstage and dynamics, then this is what you want to pursue. But if you have to sacrifice dynamics, to get low THD and thus a better clarity, then you must weigh the two against each other.
And in my opinion dynamics and soundtage wins most points.
But in the new designs it was possible to find a way to get both, so now having both low THD and good dynamics.

Hi Lars,
It seems to me this is simply the old argument of having enough open loop bandwidth... no?
"But in the new designs it was possible to find a way to get both, so now having both low THD and good dynamics."
You mean the 700XE?

Chris: 😀 good one!
No what i mean in technical terms is that removing the deadtime distortion, negates the need for high (dynamics damaging) feedback loopgain. And thus you can get good THD specs, with the same low level of feedback loopgain, preserving the good dynamics. 😎

Hi Lars Clausen,
Thanks for the wonderful explanation on Dynamics & Soundstage Vs. Resolution & Clarity.
Its very good to have both of these qualities at the same time in an amp...

soongsc: Yes i agree with you, this is a good analogy. But there is only one problem, we can't make 'digital Class A'
