Hello,
So I got a TPA3116 2x100w amp w bluetooth from aliexpress:
ZK 1002 HIFI TPA3116 Bluetooth 5.0 High Power Digital Amplifier Stereo Board 100W+100W AMP Amplificador Audio Home Theater|Amplifier| | - AliExpress
And an AC/DC 24V converter:
AC DC Power Supply Module AC 100 240V to DC 24V 9A Power Supply Board for 100W 150W Power amplifier board power supply|100w amplifier module|power amplifier dc|ac power amplifier - AliExpress
I also got some Philips bookshelf 4' bass reflex speakers, 2x50W, 4 ohm, in total everything was about 65 euro, wasn't expecting it to sound good, by I have been impressed by the sound quality and shear volume of sound coming out from these small speakers and amp. I have a Logitech Z906 and used it to listen to music, but these seem to sound better than it, especially since the speakers are two way with a tweeter.
Anyways, that was the background 🙂
Now I am looking for a step up from this TPA3116 amp, I was looking at a more powerful amp. Been looking at the TDA7498E and TDA7498 2.1 variants:
UNISIAN TDA7498E class D audio 2.0 Channel Amplifier board High Power Hifi BTL mono 220w Amplifiers for home sound systems|Amplifier| | - AliExpress
AIYIMA Amplificador Class D Amplifiers Audio Board TDA7498 2.1 Digital Power Amplifier Board|power amplifier board|amplifier board|tda7498 2.1 - AliExpress
Does anybody have any experience with them?
I am also looking for other alternatives, in the 30-50 euro range.
I also found some TAS5630 ones:
new good quality TAS5630 2X300w stereo dual channel High Power Class D digital hifi AMP amplifier board A1 002|amplifier board|hifi amp|class amp - AliExpress
But couldn't find much info about them, so any help would be much more appreciated.
For the PSU, I am thinking of buying another AC/DC 36V transformer similar to the one I have now.

What about a 3eAUDIO TPA3255 or even TPA3251? I just made a TPA3255 and the sound quality is excellent and the TPA3255 is 250W @ 4ohms with the right power supply. The 3eAUDIO amplifier modules are supposed to be better quality than the no name modules. I am a noob when it comes to all this so do a bit of research.
The next logical step up from the TPA3116 is the TPA3255. These are Texas Instrument chips and, for now, seem to offer the best overall quality. Certainly their spec sheets read very nicely.
But, please let me toss in a word of caution... If you are moving up in power you're also going to have to look at better speakers.
The TPA3116, with a 24 volt supply, regardless of what the seller says, is giving you a maximum of 50w/ch on 4 ohms or 35 w/ch on 8 ohms. While this is a great choice for 4 inch speakers, more than that will almost certainly kill them. So as you're moving up the amplifier scale you should also be ready to move up the speaker scale as well.

I watched some independent reviews of TPA3116 power before purchase, about 55w/4 ohm which is perfect for my speakers. Of course I was also considering other speakers after the amp, but those are easier to find in my region.
I will have a look at the TPA3255 and see if I can find any deals in Europe.
With the limited knowledge I have, I do believe that for TPA3255 the 3E audio boards are the best you can get for your money - even including shipping costs ;-)
