Hi!
This is my first post so i hope it's in the right place, I thought I'd just share my thoughts on this amplifier setup here as this forum was so helpful for my first setup in researching.
First a bit of context:
I needed at least 8 channels for a multiroom project at a workplace I'm at, initially I tried BalenaSound for a spotify client which went through those cheap fake texas instruments amplifiers on ebay and that kind of worked till two catastrophically failed in smoke and a bit of flames.
In the end I settled on the Aiyma tpa3255 (but the 8 channel version) after hearing such glowing reviews from ASR members on their A07. I also used a new Meanwell LRS-600N2-36 which is a 600W nominal but 1200W (5 minute surge iirc). I picked 36V as one of the reviews here mentioned less THD at 32v on 4 ohm speakers.
This amplifier worked absolutely amazingly, I mean the speakers it was driving were only 40W each but they were running at absolute max without any popping, clipping or distortion. I didn't check the chip on board but I'm pretty sure it'd original, the capacitors are branded Nichicon and it all looks well built except for maybe some thick wires jumping traces underneath the board (sorry I didn't take a photo)
For the software I used a project i put together on GitHub (although it's unstable currently its called Librespot4Pi) and it's a multiroom, multi user spotify client with in wall touch screens, it was meant to run on a raspberry pi however I ran into problems with usb bandwidth so it's now running on a lenovo tiny pc with 3 Apple USB DACs (I also tried a cheap ebay one and it was better till it overheated. I also tried the Dingshine 32bit one but it was too bulky and had poor software compatability). I was trying to keep cost down as much as possible and the apple dacs were a great value for money.
For the audio cable to each sound card, I used a shielded vga cable and it worked better than I could have hoped - absolutely no audible hissing or buzzing. And lastly for a case i gutted an old cisco poe switch, it was a perfect fit.
The system replaced an old NuVo system which already had these banana plugs in the wall.
Thank you all for your contributions to this forum, it helped me out so much!
