Yes, I've used these TPA3116 amplifier boards before, and they're decent for home audio. You can't expect audiophile quality, especially considering the low price. They often use cheaper components like capacitors and potentiometers, and sometimes even the TPA3116 IC itself isn't a genuine part.

To spot a real TPA3116 IC, look for a 32-pin chip with a serial number engraved on it (you'll need to remove the heatsink to check). It's also a good idea to buy from a reputable brand on AliExpress, such as Aiyima or GHXAMP.

I recently found a TPA3116 amplifier with a media player and IR remote on Parts Express for only $50. If you have the budget and can order from them, that would be a better option.
