Review on Nobsound TPA3116 Channel Digital Amplifier by Gary Duncan

Edit: If you look at the datasheet for this chip (TPA3116D2) you can see that when driving an 8 ohm speaker it actually dissipates 30 watts per channel and requires a 24V supply voltage. It only achieves 50 watts per channel with 21V and a 4 ohm speaker and requires a heatsink which I don't really have. The description is a bit misleading. Keep in mind, that this thing won't drive large speakers at high volume without significant clipping and distortion. Just received it and installed it using an old Sony 20V 5A laptop power supply. I had to cut off the old connector and replace it with the standard connector used in the amp. Of course, the polarity is observed. It turned on fine so I hooked it up to my speakers and it looked fine so I ended up using an adapter to connect the RCA jacks to my computer's 3.5mm mini jack output. It's very compact and still sounds pretty good. I doubt this is technically the most amazing amp in the world and I would recommend turning it off when not in use, since the electrolytic capacitors are close to the amplifier IC heatsink, but other than that it looks pretty good. I've been listening at a fairly high volume with 2 x 8 ohm speakers for about 10 minutes and it hasn't warmed up yet. Loudspeakers have no official rating,
