Nobsound Mini 200W Dual TPA3116 2.0 Channel HiFi Stereo Digital Power Amplifier Receiver Class D Integrated Amp for Home Speakers with Power Supply

The sound is clear, its got plenty of power to power my speakers. The only complaint i have is. If you have the volume at low setting. The sound will only come out of one speaker. When you turn it up little more then it kicks in. I switch the speaker wires and still has the problem. So im waiting on a replacement and ill see if it works with another one. If not ill be sending it back if it does the same thing.

The only issue I have is that the speakers make a sharp pop when I power them on or off. I've tried adjusting the volume down first, cutting power via the power cord rather than the switch in the front, installing a remote power switch, all to no avail. Sound quality is excellent with some small 50 watt JBL bookshelf speakers being used in my garage!

This is exactly what I needed and was simple to setup and use. Very happy so far.

Worked very well at first, no noise or hum. Now it's intermittent at best. I've been running a computer fan for added relief. It never got hot.Bad product, you get what you pay for.

The chips are good, the build quality is good, the provided power supply is the let down.The provided 19V low wattage power supply can not supply the amplifier with enough power. It will distort and highs will lose definition at about 2/5 volume and up.The datasheet for the TPA3116 states a maximum voltage of 26V. Nobsounds website states the amplifier can support up to 24V. Common laptop power supplies can go to 24V and are the easiest to get; if you have a gaming laptop you are half way there.After upgrading to a 24V 240W supply I was able to go to maximum volume and wattage though my Polk book shelf speakers. No distortions, no audio crackling from the under powered provided supply, highs so clear and loud I could hear them though my skull. As I was wearing double hearing protection when testing maximum volume.You need to be careful with this amplifier as with the stock configuration you could instantly blow low wattage surround and/or book shelf speakers (Allot of those are not even rated for more than 25W RMS each and this amplifier can provide more than that stock). And after upgrading the power supply you definitely will.The TPA3116 are some great chips (They can do the advertised power of 200W RMS in this configuration) when used correctly. But the provided power supply will NEVER make it there.
