so it has no DC output protection in case of a output FET failure?
I for one can't imagine an on-die failure that catastrophic not shutting down the entire chip more or less instantly -- much faster than the typical relay-dependent protection scheme often found in the Class AB world -- but maybe I'm too trusting a soul in my old age.
 
Bingo, so it has no DC output protection in case of a output FET failure? The caps are just input coupling and filtering the DC offset.
To me the absolute most important feature an amplifier should have (fire hazard, especially if you run full range speakers with no crossover).
Unless it is able to monitor it and shut off the supply voltage.
Judging by the fact it shuts down at 20Hz I wouldn't expect it to let a hint of voltage down there at DC.
That, at normal operation, but I would think TI has a pin reserved for this, I mean it has for clipping, for something so much more severe I take it for granted.
 
Would this be a good replacement for my Aiyima A07 for desktop speaker amplification?
I can't think of a reason why it wouldn't be suitable. Whether the swap would bring much of an improvement depends largely on how good your speakers are, how quiet your listening space is, and how focused a listener you are.
 
Instead of looking at % efficiency at low loads, I would proposed that the most useful metric is “on but idle” power draw measured in watts.
All of which is valid if we are looking at energy usage.

However, the point of the discussion was dissipation (primarily) in output stages resulting from a discussion of thermal risk from higher power supply voltages. In which case looking at pure amp efficiency is valid. I accept that the chart I posted for the Yamaha doesn't give that.
 
I just finished reading the Topping Mini 300 review, which I thank you for. The results are truly great and after seeing that kind of power and performance, I honestly cannot see the reason they named it 'Mini'!
It makes me wonder: would we be meeting a B300 along the year to follow up on the B100 and B200?
 
I honestly cannot see the reason they named it 'Mini'!

They are going with the 'truth in advertising' approach to condition people to be prepared for a very small amp. The main unit is similar in height and width to four CD cases stacked on each other, but a bit deeper.

It's the same figurine in the pics below...

..and then you connect it to real speakers and it sounds like a** , nowhere near to how real 100w 8ohm amps sound like.
 
... Tho I agree that Toppings power ratings are "questionable". As are many manufacturers.

Well if you are trying to get 100W at 8ohm from a 50W at 8ohm amp, that would not be a huge surprise. It will be clipping like hell.
 
I also don't get the "amps" that are unable to drive bass drivers, deliver tenth of power to the bass or start distorting over 6KHz. Cheap in the end results being expensive.

Why are we letting d-class amps pass when any AB amp would be chasticised if it had that same behavior?

No one is immune to it, icepower gives power figures for 10% THD+N along with the normal 1%THD+N for mine for example :facepalm:
And they conveniently name it after the power it gives when one channel driven (burst of course) .

You have to dig datasheets to know.
No virgins at this business.
