I have a project for which a TPA3116 or TPA3118 would work beautifully - I really don't need that much power. However, after buying a Bluetooth amp board with obviously fake amplifier IC (KKmoon - did weird stuff on the oscilloscope), I'd like to buy one that isn't total junk.
Can anyone suggest a retailer for these? I hear the Sanwu stuff is quality, but there's an awful lot of lookalikes and fakes. Also, can anyone suggest a cheap SMPS?

Same here... looking to build an Arcade Cabinet, seeing a lot of the TPA3116D2 2.1 amps on eBay cheap, but, although I don't need anything spectacular, I'd rather pay a bit extra and get something good than pay $8 and get something that's just flat out awful.
I had two failed tpa3116 2.1 boards also. For kicks I ordered a mono 3118 and 3110 and I already had a mono 3116 from another project and all of them seem better than the 2.1 boards. These mono boards are very simple. I am suspicious that they are better out of the box as the manufacturers have less corners to cut. The 3110(from hiletgo amzn) is my current favorite as it has virtually no noise or hiss. The 3118 did pick up a touch of Psu noise (some supplies had no noise others did). None of my testing had been scientific just a temporary hookup to an efficient 4 ohm speaker and a very inefficient 8 ohm. With efficient speakers the 3110 was fine. I need to test the 3118 some more.
Regarding the 2.1 noise, I'm looking for a proper implementation of master and slave mode which I think we need to update the wiki http://www.diyaudio.com/forums/diyaudio-com-wiki/252663-tpa3116d2-boards.html
