🔊 Fosi Audio V1.0B Black 2 Channel Amplifier: Mini Hi-Fi Class D TPA3116 Amp with 50W x 2 Output for Home Speakers – Includes 19V 4.74A Power Supply Review

I have salvaged some 25 year old Dukane AM/FM radios from a hospital sound/music system. The amps were bad, but the receivers were in perfect condition and looked brand new. I ordered one of these audio amplifiers to see how it would work with radios. The results are better than expected. The sound is very good even with a bundle of wires connected to old car speakers lying on the table. There is no interference even if I put the amplifier on top of the receiver. The on/off mini toggle switch…

My speakers quickly started to sound bad. My main amp fell apart. Unable to deal with it and unwilling to buy a new amp in the long run I decided to try this little advertised 50 watt D amp. I wanted to make sure my old amp was really bad so had my system to go made to run . Surprisingly, it rocked my speakers and didn't sound terrible. There were no signs of previous versions, so this was done in no time. The amplifier is so small, a little bigger than a pack of cigarettes, that you don't want

Firstly this isn't a 50 watts per channel amp, it's probably more like 15-18 watts if you're using an 8 ohm speaker which you probably have. Now that it's ruled out. It's an amazing piece of engineering to squeeze so much sound out of such a small amp. But this isn't the A/B booster most people are used to. It's a Class D amp. That means it has virtually no headroom. So if you listen to music with loud transients, such as classical music or especially piano music, you will miss this dynamic…

Let me start by saying that I also bought a Fosi Class AB amp and I really like it. After watching a YouTube video showing the difference in sine waves between a class AB amp and a class D amp, I understood why class D amps have more distortion initially. Other than that, I don't know what the electrical engineers at Fosi did, but the sound you get at this price point is amazing! The first thing I did was plug it into a 24 volt 5.7 amp power supply from my SMSL AD18. Compared to the included AC

Okay, I've been living with this for a couple of weeks and I'm really impressed. My background is a former budget audiophile who hasn't managed to build a decent system in six years - and decided to see what ChiFi is about. The last system was a vintage Amber Series 70 amp/Parasound/NAD CD/Magnepan MMG preamp and I compare it to my memory of it. I connected this Fosi AudioTPA3116 based integrated amplifier to Q Audio 3010 and Chromecast Audio speakers. Q Audios are small enough that I can't…
