What are your thoughts?
Magic ? !!
Class D equivalent to the DIYA "Wolverine" !

At 86W , more like any of my smaller AB designs (spooky/slewmaster - all) - 1-5PPM.

I already have Topping E70 Velvet DAC. Now, I can listen to that amplifier and build DIY amplifiers purely for fun, just to see how close/far they are from B100.
We should seriously reconsider our perception of Chinese quality...
Tested recently over at AudioScienceReview where it measured better than almost any other amplifier ever made. Believe it or not.
https://www.audiosciencereview.com/forum/index.php?threads/topping-b100-amplifier-review.57036/
THD = 0.000216% at 5W output into 8 ohms when set to its high gain (25.9dB) setting.

Medium power(80w) monoblock with an external power supply…..I cannot stand external power supplies.
Not for me for sure.
But the specs are amazing indeed.

Nice finding: it's beautiful, it offers extraordinary performance, it is mono and it doesn't cost too much, it is not Class D as we all (I guess) thought at first glance, but as someone already said it is Class B.
You just have to try it or wait for a review of how it sounds that doesn't seem to be around yet.
If you find a shop that will let you try it and then possibly return it I would do it immediately in your place.
As you know there is also the B200 which offers double the power, same performance and double the price.

You know, this isn't ASR so not a commercial product discussion forum... just saying... in this subform, we discuss DIY of solid state amplifiers.

This is just ridiculous: didn't it occur to your mind that this device could be even modified in the full spirit of DIY?
If you have nothing better to say, why do you do it?
Just to show off?
What would repairability (is that a word?) be like in case anything burns out? Are there any Topping specific parts in there that would require their supply? They have a slightly less than optimal history but it's probably meaningless unless compares failure/sales rates.
@Logon What could one change other than up power? It measures as perfect as can be (genuine question).
What I find interesting as a complete electronics dumbass is that designers have worked for decades to reduce overall feedback in order to get better (perceived?) sound quality. Here is Topping reversing this completely, with high feedback, apparently.

Since the comment I replied to was in my opinion so generic, my reply was also a generic one.
However, you may want to modify it in various ways just as all so many amplifiers are often modified.
I didn't think about modifications made immediately after purchasing it (although I don't rule out any possibility), I'm thinking about how it often happens that after having it for a while you think about how to further improve what you have regarding the related SQ.
You can start simply with a higher quality or different material of the binding posts, for example.
Or the replacement of components with others considered of better quality and SQ, etc.
In your specific case, assuming that you would buy that amplifier, there doesn't seem to be much room for modification, but neither does any.
Not to modify the numerical performance, but the acoustic one, at listening it.
I'm not inviting you to do it, I'm just giving examples of what can generally happen (or not happen at all).

Its a composite amplifier, Topping calls it NFCA (Nested Feedback Composite Amplifier), according to their website. 😀
Perhaps using an opamp in front slaving a simple discrete (or chip) power amp to dump current into the speaker. That's why it could achieve such a low distortion.

Aren't the five units at the top of the photo, just behind the balanced input, switching relays? Why would they be there in such numbers in a mono power amplifier? Perhaps they are something else?
I have a pair on the way... ordered them early last week, but I still don't have a shipment confirmation / tracking number.
It was intriguing enough for me to give them a whirl.

"Not to modify the numerical performance, but the acoustic one, at listening it."
This is a piece of electronic equipment, it cannot be modified acoustically, it is not a acoustic transducer like a speaker. You can modify it electrically but if it is that "perfect" already, what is there to modify, you might just degrade its performance.
When you buy a car, a food blender, TV , watch, is it your first response that you want to modify it? Then why buy it at all. Buy an empty container and you can place whatever you like inside and then modify it at hearts content. ItsAllInMyHead enjoy your new amps and kindly comment your pleasure or displeasure of your acquisition when you receive it.

Is pretty much what I've asked before but what if that measured performance does not result in listening satisfaction for the user? For example, I believe many designers of amplifiers have for decades tried to overcome large overall feedback, which, to some, results in a less than stellar sound. Topping, as far as I can understand it, have used very high feedback on this amplifier. You could argue that one perhaps should not buy this in the first place if you are against this but would it be possible to change this feedback behaviour for this Topping amplifier to make it sound more 'pleasing' (whatever that means) for the end user even if measured performance is compromised as a result?

Looked at specs and test. I cannot recall anything seeing like that. IMO, those relays may be related to gain settings since it has three setting it may switch some low noise ladder of resistances. Cannot think why else there are so many relays.

If you haven't heard it it is pointless speculating about it. Maybe it is the closest thing to a wire with gain and it shows up only the shortcomings of the rest of the chain of components in the system. Problem is now you have to re-evaluate and even replace everything else you have because it is inferior. Who knows, it is easy to speculate, hard to prove. Amir's reviews and reports are virtually only objective and only thing that can be proven repeatedly. Subjectivity goes out the window.
That topping could not be a typical class B -
- not enough heat sink for that power level , thd too low.
I suspect it is some hybrid , since topping calls it "T'ang Ku LA" topology - WTF !
Micro controlled proprietary AB "like" topology. NFCA Nested Feedback Composite Amplifier ??
That is a loose description of the wolverine "TMC" - What BS.
I'd like to see one stripped naked.
