Hello. Please help. I have been using fosi v3 and aiyima a07 for a long time. I have wharfedale xarus 5000 speakers. Before that, I used less powerful ones. The problem is as follows. Firstly, aiyima burned out after long-term operation at high volume from a 48 volt 10 amp power supply and got very hot, after several attempts to force it to turn on due to overheating, the tpa3255 chip went to another world. Fosi behaves approximately the same way, but allows you to make it a little louder by a couple of decibels and also turns off. What should I do, how to feed the speakers? If I buy a pair of fosi mono, will they be able to pump up the speakers without turning off? (long-term loud listening). Moreover, the current amplifiers turn off earlier if you add even a little bass. I need a powerful amplifier that will provide long-term play at the maximum of the speakers. Sorry for the bad English, I am writing from a translator.

Hi, I think you should work out why you need so much power that you are overloading your amplifiers.
Your speakers are fairly sensitive, you shouldn't need powerful amps.
How far from your speakers do you sit, and how large a space are you trying to fill? How loud do you play - can you hear yourself speak over the sound?
What you are finding, shouldn't be happening.
Can you tell us anything more about your equipment? What do you use as a source?
Otherwise, the Fosi Monos do provide more power. You could also look at something like the Beringer A800 too - a robust amp that measures well.
I'd want to know why those amps burned out before I bought another.

Quick question - do you play very bass heavy music? Low frequencies are harder on the amplifier.

I believe that this is so, but with all this, at the conditional maximum of the amplifier (the moment before it turns off), there is still a reserve and the speakers will play louder (no distortion!). Therefore, there are probably amplifiers that can load speakers to the conditional first distortion.
The living room is large, approximately 30 square meters with a ceiling height of 3 meters. And it’s not about where you sit, sometimes guests come, you want to start dancing to the fullest. And at some point, during the bass line, there was a CLAP and everything turned off.
Source ANDROID TV with Apple Music application, with optical output, then preamplifier topping d50 (-3dB) + fosi sk01 (tweet +0, mid +0, bass +0). Sometimes you want to add bass +1,2,3.. due to the absence of a subwoofer, and then the amplifier turns off much earlier, although according to the sensations the speakers CAN! There is no distortion... I can hear it well.
Fosi is still alive!
And Aiyima a07 experienced several shutdowns in a row (probably due to overheating), after which a smell began and did not turn on again.
etc: Of course, in ordinary life this volume is enough, but sometimes you want to surprise. Could it be a cooling problem? If you force air on the chip, then perhaps it would make it possible to listen longer and louder? Or is there a problem in the level, there is some kind of INPUT level that tpa3255 is not ready to digest.

I'd like other members to give their opinion too.
Playing loud music in a room full of people (all absorbing sound), especially with loud bass, takes a lot of power.
You could add subwoofer(s) as long as you had an amp or DAC/preamp that can high-pass your main speakers - relieving them of the strain of reproducing bass.
I think I'd want an amplifier with some pro-audio features: good protection circuitry, clipping indicators and built to play at parties.
That Behringer was well reviewed here
Thread 'Behringer A800 Stereo Amplifier Review' https://audiosciencereview.com/forum/index.php?threads/behringer-a800-stereo-amplifier-review.10499/
Alternatively, look at Hypex power amps like NC502
The Fosi Monos do have loads of power, but I'd worry about their ability to maintain high output for long periods

This is a tell here. And with EDM also
Your speakers may be able to respond to the bass - but they will require a lot of power to do it. And when you crank specifically the bass even further, then you are going to reach the limit of what these small amps can do very quickly. It is after all only good for about 120W into 6ohm.
If you want to play at those levels with elevated bass, you are going to need subwoofers (and to high pass the mains) - or a much more powerful amp. For example, one of the newer hypex or purify based models capable of 400W or more into 4ohm.
But Subs are a better way of dealing with what you are trying to do IMO. Although - depending on your expectations you may need both subs and a more powerful amp.

I would like not to lose the quality that Fosi really likes. Judging by the review, there are certain disadvantages.
Adding subwoofers to the chain is definitely planned. However, I still don't understand why Fosi can't maintain consistently high levels for a LONG TIME. I want an amplifier that is as good as the Fosi sound quality, but at the same time more powerful.

There's an established saying: good, cheap and loud ... You can pick two (but not all three)
Hi.
I think @JeremyFife's recommendations are the way to go.
The Ayima configuration, I think, used 63V capacitors, one rank above the Ti chip.
For intensive use, professional components are recommended, although compared to hifi equipment in some cases they have different performances.
The protections in the pro power stages work very well and also have a higher power reserve.
Here is the inside of an ECLER XPA3000 stage, with a good toroidal transformer and a power reserve.

Because you are driving it past its thermal design limit. The power levels you want can't be sustained indefinately. The amp is over heating and self protecting by shutting down.
Yes, that is what you need - as I suggested.
Perhaps a little - but not much. And do you really want to be operating this little amp so close to its limit all the time. In addition to the thermal limit you are almost certainly driving it to clipping and distortion.
I'm pretty sure that I can predict what will happen when you add a much larger amp to your system: it will blow the speakers! These are not speakers for parties even if they can take a bit of a beating. But with the current, clipping low-powered amps, it's a miracle that the tweeter is still alive!

A room with some people playing EDM won't even cut it with subs if the mains are not powered enough (and can stand the power) .
There is a gazillion times I measure the voltage down low and then mid-high and the power needs are pretty much the same even if my active's x-over is at 240Hz.
What you need is an amp with thermals and protections kept at check.Choose the best cooled and with fair amount of power.
There's absolutely no point having an amp going to 120W if it's for milliseconds,it would be far better to have a 50W continuous one.

And another.
At the power ratings thread I showed examples of what EDM is.
There's people even mixing white noise (!) in these works (Seven Lions or something is the band,I don't judge,I won't be the grumpy old man ) so we better forget about the clean bass-one female voice crying-2 1/2 more instruments music.Think big.
Dear OP,if I was you I would get the biggest,baddest Cerwing Wega's ,a bunch of fuses,hearing protection and a pro amp and call it a day.

It is a good point.And another.

@activio - if you want dance club levels of volume, you need dance club levels of gear. And hearing protection for you and your guests. Don't do what I did and end up with tinnitus for the rest of your life.
