You have to know what you are buying...there is a good deal, if you have a minimum of knowledge...
Hi I would love to see a picture of the innards of that one. Did you disassemble it?
I disassembled mine. It consists of two boards connected by a ribbon cable. The main board is basically the amp with inputs and power connectors. The speaker connections are the four large holes in the board - these connect to the speaker terminals when the board is mounted into the housing. The 2nd board has the LED driver and bluetooth chips. The housing has the four speaker terminals and some threaded bolts glued to the bottom to give it some weight. 🙂 Lots of electronics for the price! I haven't done any testing/listening as I'm deep into a speaker project.

There are worse layouts out there. Thermal stitches seem OK too. Also it has output filtering not found in more expensive amplifiers. The costcutting already started by leaving out some decoupling caps. Low cost and high modding potential.
Maybe the more noisy MA12070P is more quiet in reality when compared with devices that use MA12070 without any filtering….
Thanks for the pictures ernperkins! Please tell us how it performs.

Admittedly.. but I prefer the A/D conversion to chips provided for that... If infineon brings me a new chip with dac AKM inside.
i sign it According to the specs ... we can do without filtering or reduce it to a minimum ... it was a bit of their commercial advantage .. ??? 🙄 🤔🤔🤔

It could be that O-Noorus also is a sub brand of the same factory that produces these devices under various names. They have similarities and advertising also has similarities.
The question is if they use output filters.

@jean-paul you could be correct they all looks the same under different brands, most probably manufactured at the same place here is another from brzhifi

Just need something can be easily modded or minor mod and use as a soundbar replacement, 2.1 with remote control under $150

The old Sabaj A10a has remote control and a subwoofer line output. The one I now have has been modded and it is a nice amplifier after that.
I saw there is a thread of the old A20a mod, between the old A10a and old A20a which would be easier to mod with phenomenal results?
