He also ascertained that you can fry one by pushing it into protection repeatedly... so I guess the lesson is don't do that.Looks like Erin from Erin’s Audio Corner has ascertained that there is, in fact, a measurable improvement using two separate 48V/5A power supplies rather than a single 48V/10A supply for two amps at once:

Yes that just seems very…extra.He also ascertained that you can fry one by pushing it into protection repeatedly... so I guess the lesson is don't do that.
Welp, I changed my pledge to two 5A power supplies. Not just because of this - I was on the fence already. There’s too much uncertainty with the single 10A power supply for me. The cords will be hidden anyways in my set up so it’s just a matter of taking up an extra outlet.Looks like Erin from Erin’s Audio Corner has ascertained that there is, in fact, a measurable improvement using two separate 48V/5A power supplies rather than a single 48V/10A supply for two amps at once:

Erin is easily among the better reviewers because he actually cares to measure, usually he has more on his website but so far nothing on thisit's very mediocre review, much needed measurements, but overally mostly irrational complains (this amp has 200W, oh i like 500W! Thats how quirky I'am - might be the stupidest thing said by the reviewer i've heart this year) Also measurements without any comments or context: oh the graph look like this, now f*ck off. And also Fosi stop sending mi these i don't like to review this amps (Wtf?). Oh, and one got fried, haha, so funny. I haven't seen such an unfair review in a long time.
But apart from the diva rewiever, looks like two power supplies is the way to go (5A or more).
I saw almost all his reviews and cant remember as bad as this one. It seems that even a review based on measurements can be covered with subjective, irrational gibberish if for some reason someone feels the need to do so:Erin is easily among the better reviewers because he actually cares to measure.
We know that, but most people probably doesn't know that, so his review is very very misleading.I don't care that much that one of the amps got fried because when watching movies or listening to music it be anywhere near the same load as his tests..
People are all over the place so it's good to point out that it's not sensible to drive subs with these for example.We know that, but most people probably doesn't know that, so his review is very very misleading.
@Fosi Audio 's silence these days and the new measurements have convinced me to change reward from single 48V 10(?)a to double 48v 5a
The problem was not the PSU,the problem was heat by driving it repeatedly to/or near to it's physical heat dissipation limits.Also i understand that the problem was mostly using one power supply for two amps, that what fried it. With two separates everything was grate?
The chip itself HAS thermal protection,he states so as it kicked in some times. TI's data sheet is clear about it.Yeah, it's a little worse than not fair to look for the limitations, push it over the boundries and than complain that it can't handdle it. No surprise there. But at the same time something that might have been prevented by some form of thermal protection.
Yeah, but the protection kicked in several times during using one power supply for two amps (as for other reviewer posted here), and then one amp fried? With one power supply per amp everything worked fine.The problem was not the PSU,the problem was heat by driving it repeatedly to/or near to it's physical heat dissipation limits.
It's about time.No matter what PSU used,if it could bring the amp to/near it's limit it was just a matter of time.Yeah, but the protection kicked in several times during using one power supply for two amps (as for other reviewer posted here), and then one amp fried?

isnt that quite the opposite?No matter what PSU used,if it could bring the amp to/near it's limit it was just a matter of time.
No,the amp doesn't care about the PSU as long as it is adequate.isnt that quite the opposite?
One psu two amps can't drive amp to its limits, but can fry it - but one psu one amp can drive the amp to its limits and doesn't fry it...
