My approach is to have no opamps in the signal path and so far it has sonically payed off. That might change as I tried those fairly new ??1665 on one of my TPA 3255 and they are so good that I might consider them for my less sensitive speakers.
How do they manage this in the integrated chips containing both dac and amp? Wouldn't they have the same issues?
There is no "fuse" when things go wrong. Anything offered at the input will be amplified full volume.
Yes I understand but opamps are not necessarily evil. I think you mean OPA1656?! BTW you can edit your own post just after you have posted it to correct spelling errors, mistakes etc.
My MA12070 device will have solely transformers/caps and I am curious if it will work out.

in my opinion. All single power amplifiers. They are just toys.
No manufacturer will use these things. Unless it's on the car.
For example, Jeff rowland Or arc 😛
In my cognitive range. All single power supply amplifiers. They are just toys.
Want a high-performance amplifier. Dual power supply must be used.
For example, Jeff Rowland 250 class D
ARC DS225 , DSI200
In my impression. Iraudamp4 and iraudamp5a are the highest performance amplifiers in the world at present.（CLASS D）
of course. It does not include ma120 mentioned on your website. Because I don't know this model. But it should be strong.
For being “toys” the TPA32XX amps are kicking some real commercial amps’ butts. Look at performance of Topping PA-5. Almost up there with Benchmark AHB2 which is nearly 10x the price. Other TPA32XX amps are also out there with rave reviews and another one was directly compared with AHB2 and others like NAD, etc. and all lost.
Performance means nothing when the product is of poor quality and breaks down quickly (see thread on ASR).
I have not been following PA-5 but just saw it’s performance measure very well. These may be isolated instances but agree that customer service should be better. There are other more substantial alternatives to the that are more reliable in the long run and have rave reviews and with customer service and warranty repair based in the US. The MA120 might be a closer contender but I feel the max power levels may be a limiting factor.
New Merus chip MA5332MS rolled out recently and some products about a month ago. Sabaj A20a 2022 and some sisterbrand model A300. Supposedly similar as MA12070 with more output capability.
The question is if course if the recent chip is as good as the old one. If not then MA12070 has a chance of TDA status 🙂
So single power supply amplifiers are toys?! Does this include JLH and Pass designs? Probably a misconception what “high performance” exactly is.

I am looking for sonic performance not for muscle amps that need to move 200 grams paper with 85db efficiency.
The new Merus chip is actually even more to my liking than the previous one - more power and thus control, but also extremely balanced and no harshness.
I see the MA5332MS can be used with a split supply. That should make ljm_ljm happy.
Why am I happy. boss.
I don't have ma5532. Is it the same as ne5532. Please don't blame me for not understanding 😈
In fact, you said what I thought. JLH pass.
But I dare not say so. I'm afraid someone will hit me.
Well... the NE5532 is for pre amps and can not output any current worth mentioning, the MA5332 can churn out 2x100W.
Seems to me like you are (very) intentionally misunderstanding, probably very funny but the joke does not really translate.
Find it somewhat peculiar that you are fine with making obvious and perhaps boundless insinuations but do not wish to stand by any "conclusions" derived from what you say.
Again, if this is humour - does not translate.
You are entitled to have your opinion, and you can speak it freely (within the forum rules), but merely having an opinion does not mean people will automatically agree to it.
I would be interested in what you think are the important aspects/differences between what you differentiate as "toys" and "proper" amplifiers, but if it comes with a sales pitch (starting to seem like it...) I have no interest in that.
Let's focus on MA12070 and all the products that use the chip OK?
