Im in for a fairly powerful class d amp for under €100 or £90 for my low sensitive speakers
So fare i have found a FX-AUDIO FX1002A and a Fosi audio TDA7498E amp within my budget
Some say smsl amp below the FX1002A can have have channel unbalance and hiss
The Fosi amp seem to have gotten som improvements like this over the older version but is it better than the cheaper version of the same amp like the one from breeze audio
The fosi amp only comes with a 24 volt power adapter where the fx audio amp comes with a 32 volt power adapter
hiss and channel unbalance ?
What is the amp to go for ?

Look for an amplifier based on TPA3255

I want to avoid buying from china (outside of europe) because of the risk of having too pay import taxes and handling fee = almost 50% more expensive
No thanks, to expensive and takes to long to arrive

Regarding cost/performance. Hard to beat the img sta-400d which use hypex modules.
Edit:
Not from china, you know what you're getting.
Good s/n figures.

Why ? The behringer A800 is cheaper and more powerfull, the same goes with a Crown XLS 1002 + it has dsp so it's possible to use a high pass filter for better sound and more power

I will not go into a debate about Behringer, they focus exclusively on "value for money", nothing wrong with that but then you might as well get the TPA3255 made in china version (quite alright if you know what you're getting into, works well enough, I've used some of them myself).
On my list the Crown XLS is of higher quality and you get DSP, so "not bad".
The hypex modules in the STA-400D are well known. Perhaps it does not seem like a big difference between the noise figures on the Crown XLS, but the slightly improved s/n takes quite a bit of effort and is well worth it IMO.
So in sum (insert personal bias):
TPA3255 is the best value for money, and you can get very good TPA32xx amps if you are willing to pay a but more than 50 euros...
I do not purchase Behringer products, some people are happy with them.
Crown XLS slightly more reliable and with DSP integrated.
Hypex (or Icepower for that matter, perhaps also Pascal for a bit more) are higher performance modules that demand a higher quality signal chain to really shine. A really well implemented TPA3255 can be almost equal to this level of performance.
Up to you what you want, and how much money you want to spend.

well i don't need more power than i have, my new Fosi Audio TDA7498E mini power amplifier is quite good

Not sure why you waste our time asking when you have already decided, bought, and solved your problem. 😕 🙄
Not a waste, hundreds of other members also benefit from such threads!
Thanks for your contributions too
Try reading some of the reviews of the amp i bought, it's a very good amp
Atm i only use my pc,cdplayer and because i have an external dac i only need one input but i have cable and a selector box + a phonostage if i need to use my turntable or cassette tap deck
Im impressed about it, i use a tube buffer with 5654 tubes
5654 6AK5 CV4010 JAN GE MATCHED PAIR NOS BOXED VALVE/TUBE | eBay
I was worried about distortion and not having enough power, although i use a tube buffer which makes it twice as expensive and have 85 db speakers it can play really loud and it sounds soo good i wonder why you would buy a 20-30 year mid range full sized amp for the same price

So you talk against buying a china amp, and then you go and get one.
These little amps are great value for money, and with your tube buffer it is very likely that you will not benefit from choosing an amplifier with a lower noise floor.
Nice to know that you are happy with the purchase, but i agree that the thread is pointless since a huge amount of threads like this pop up repeatedly, and at the same time you asked for advice without explaining the signal chain in detail. Then ignore the replies you get.
You also asked for a high power amp, this implementation of the TDA7498 that you bought will probably be able to cough out ca 40watts per channel, which is more than enough for most, but it is NOT high power.
Again, very nice that you found a suitable amp for your needs, but the thread is almost completely without value.

It's an amp bough from china (outside of europe), because i don't want to pay import duty,taxes and handling fee when buying out side of europe, that can make an already cheap amp,power adapter something like €40 more expensive
25% import taxes,duty and handling fee is €22 if they got it and can see it's not bought in europe.
I bought it from europe, amazon.de (express delivery + around €3) italy too germany, germany too sweden, sweden too denmark and than too where i live in denmark.
Why would i explain the signal chain in detail ? pc-digital cable-dac-analog cable-tube buffer-analog cable-amp - speakers with qed speaker cable and isoacoustics stands
I wanted a power full amp 8rated at 2x100watt or more) since most below €100 class d amps don't play as loud as rated unless it's 36 volt or higher in 4 ohm with 10% thd
The best TDA7498E can handle 36 volt and delivers at that voltage over 2x100 watt in 4 ohm, i desided not to buy the FX-AUDIO FX1002A TDA7498E that comes with a 32 volt power adapter based on reviews,respons from people who have one, some say i can have not the best sound (TL082CP DUAL JFET AOPs) mabye hiss. (channel unbalance? )
I just read some comments that made me not buy the amp !
Even when i have seen the impedans of my speakers i don't know if it's more a 8 or 4 ohm amp load
I am how ever considering a 32 volt power adapter, i don't want to over load the amp and risk it getting super hot buying a 36 volt power adapter, not from outside of europe sine it can add 25% import duty,taxes and €22 handling fee for someting that costs under €30 with shipping
Normally i have my full sized hifi amp lowered by -10 db to match gain.level too my turntable, even than i can go above 12 o'clock and have it very loud, i just for some reason having a louder experince with my mini power amplifier.
I still consider despite that louder experince, getting a 32 volt power adapter i just like to know if people also get better sound quality with a higher voltage power adapter,if it gets very hot playing loud with 32 volt (not full power just loud) would also be nice to know

I have no problem understanding that you want to prioritize speed of delivery in combination with taxes and transport cost, but then there's no point in mentioning China at all.
Because it will inevitably be relevant to the suggestions you receive.
I sincerely hope you did not spend a ton of money on a high quality dac, because with the other components listed it would most likely be a complete waste. You would most likely be unable to discern any actual difference between something like a Khadas Tone Board and the somewhat random quality headphone output of an average laptop, provided there's some level matching. No offense intended, despite how it may seem.
But when you calculate losses in the design and the capabilities of the power supply, in combination with the fact that you did not buy "The best TDA7498E", you're stuck with different numbers. To me this is like a Pear to Watermelon comparison. You can choose whatever amp you want, just want to make sure you understand that there's a lot of wildly different implementations of the TPA32xx series and the TDA7498 or equivalent. Some are crap and cannot possibly get close to specsheet numbers, some might end up producing the magic smoke if you try.
I purchased a decent but cheap TPA3255 implementation from china and eventually ended up getting a proper 48v 8a psu from Elfa distrelec on discount. The psu arrived the next day shipped from the Netherlands.
Before you go about ordering a power supply you will actually have to open the amplifier and check to see what kind of components you have in the PSU section, or you might end up with a nasty surprise.
Despite what you might think, I am interested in giving you a realistic expectation, not trying to talk down the TDA7498E. Only saying that no matter what kind of chip you're using it depends on the circuit and surrounding components if it can come remotely close to (underperforming), or perhaps even in some rare instances, exceed factory specification (it happens, but not frequently).
Most amps are made in china and even from usa it's outside of europe
I got more money selling my old dac than the new "used" dac cost me
I didn't buy the cheapest amp i could find (eneither the most expensive), the one i bought is very good but not as expensive as something like the Topping PA3, some like the PA3, some don't (Topping PA3 has som hiss i don't notice from my amp)
Topping PA3: subjective impressions | Audio Science Review (ASR) Forum
I wouldn't go so extreme to buy and amp and use it with a 48 8a power adapter, i would be affraid it would get so hot playing normal loud i wouldn't be able to touch it

Seems to me you are having a different conversation than the thread title suggests, and it also seems that you have no interest in the more technical sides of the hobby, which is perfectly fine.
Even though you are quick to defend yourself and reject whatever replies you get, I hope you are happy with the amplifier but pretty please with ribbons and bells on check the internal psu section of the amp before ordering a higher power brick.
Most people do not need 100's of watts to listen to music, and it seems like you inadvertantly just figured that out. I think you would be equally happy with a well-built TDA7297 which is an excellent amplifier chip but slightly less power class AB.
