Right the only secret are the op amps in the D01 small box. I was thinking about differential op amps....
Probably OPA1632 and feedback from TPA32 output ... to OPA input.
L'ampli a été ouvert, le dissipateur thermique retiré, la puce clairement identifiée par son marquage supérieur, enfouie profondément quelque part dans le fil ASR.
La puce qu'ils ont utilisée n'est pas l'élément clé, les détails de mise en œuvre le sont, et Topping n'utilise rien de ce que vous trouverez directement dans les fiches techniques et les notes d'application.
Well, he specifically said that if someone desolder the chip and replaced it with a TPA, there will be no sound..He talked about chips under a cover and a new way to reduce distortion, his patent.

Why all this French all of a sudden? KSTR never said that - did he? Thats a false quote.
2 violations of the forum rules in one post - congrats!

Wrong use of the Google translator, I would say. Many posters use the translator instead of writing in English.Why all this French all of a sudden? KSTR never said that - did he? Thats a false quote.

“OMG better figure out how Topping did it because there’s a very strong market moving forward for 2 channel amps built outside of China“ Said the ignorant soul.
Funny stuff. I see myself being quoted in perfect French here, and in perfect Polish over at ASR, haha.
Sooner or later the secret will be revealed, I don’t know why it is necessary to be secretive about this.Well, he specifically said that if someone desolder the chip and replaced it with a TPA, there will be no sound..

Probably because you never designed and sold something.
//You are despicable ... your discussion brings NOTHING ... 🙄 🙄 🙄🙄
Truth hurt at times... and I said "probably"... I adjusted to the level of the discussion at hand - sorry!

Because things that measure well, USUALLY don't sound bad! And the inverse is also true. If it measures poorly, in all likelihood it will sound bad. No offense to all the tubes lovers here that want that warm (harmonic) tube vibe. And, in the end, mods can go sideways, and then you end up with one or more unintended negative consequence to your original mission. But hey, this is DIY after all. 🙂 In many ways, some mods start to push the envelope of diminishing returns. And some reach the nuanced improvement level and expectation bias starts to set in. We WANT to hear a difference, therefore we will. Just say'n. 🙂Eee, how do "we" know this?

Edit. @TNT I was still composing when you posted. I agree with much of your post above.

In our time of information technology, nothing can be hidden. On the contrary, being open, sharing knowledge and information will make you rich.
This amplifier for $ 350 and with big secrets would rather ruin the manufacturer.
Not necessarily .... But it allows you to get an idea ...
Personally if it's a TPA 3255 chip ... I don't buy!

Hi mamocel, as you must know, I have a Sabaj A20a and I am completely satisfied with it, it is plugged into my secondary chain.Not necessarily .... But it allows you to get an idea ...

I think like you, if it is a TPA325x, I do not buy because even if the sound of the PA5 is good, I pass my turn on this chips.
I am also waiting for the subjective feelings of Daniboun, because he owns the A20a, he will be able to compare.
