All modern amps are current limited (due to short circuit protection), so the main question is to know below which impedance it is the current limit that will limit the power instead of the power supply voltage. If it's too high for the mated speakers, better look somewhere else.
Of course there’s current limiting -every amplifier has some form of protection. Whether it's an impedance or current sensing circuit, rail fuses, output transistors, rectifiers, the mains fuse, or even a circuit breaker on the AC line, something in the system will eventually impose a current limit.
Ideally, these protection mechanisms should recover automatically and gracefully -without smoke, failure, or any real inconvenience to the user.
The reason this matters in the case of the Topping Bxxx amplifiers is that their current limiting kicks in under fairly benign, not extreme, speaker loads. That raises the chances of users experiencing unexpected shutdowns -and that's something worth pointing out.
As I said when the B200 Monoblock was reviewed: it's realistically a 130–140 W amplifier with limited headroom, and it’s not suitable for low-impedance loads.
This becomes evident when comparing its power output into an 8-ohm load at a 60° phase angle versus a 4-ohm load at the same phase angle -the power output actually drops.
And since it's a class A/B amplifier, you also need to factor in the EPDR of the speaker load.
In short: the Topping Bxxx series is designed to excel in low distortion and noise measurements -and they do that very well -but their current delivery and load tolerance have real-world limitations that should be considered and matching speakers should be done with this in mind.
That’s why I specifically mentioned a complex load below 4 ohms -not as a wordplay, but as an important distinction. It is word play. The only accurate thing you can say is that it has difficulty with 2 ohm and lower. That is the only data. 2 ohm capability goes well beyond capability of...

Exactly. If you go from the Clearly Lying spec sheet it is 200W on 4 and 8Ohm And as amir said "You would need even more voltage for 8 ohm" means in vice versa you need less voltage for 4 ohm to reach max power If you go from the measurements you posted not that i said What is a...

I totally disagree. Hermes bags, which cost 30,000 euros, are assembled (material and labor all included) for 35 - 40 euros!!! Absurdity! But that's another topic. I mean did you really read that? Would say it’s spot on for many extreme luxury products. The manufacturer shortens the supply...
