    • Awesome Value and Quality

I had some extra bookshelf speakers laying around and wanted higher quality sound for my office computer. This amp is everything I needed and nothing more. The Bluetooth option is cool and was very easy to connect to, but I'm primarily wired to my computer. I hooked this up to a pair of Definitive Pro Monitor 1000's and they sound amazing. With my computer volume at 100, I can only run the amp volume at about 1/3 before the speakers vibrate off my desk. For a simple setup like this, this amp is perfect. ... show more

They promptly sent out a replacement, ensuring that the minor setback was resolved efficiently and I could get back to enjoying my music without delay. Fosi Audio's willingness to stand by their product and swiftly address any issues is highly commendable. It's a testament to their dedication to providing a top-notch customer experience, further adding to the already spectacular appeal of the BT20A.

This receiver produces better sound quality than a $300 one. So far, the Bluetooth connectivity has been great. Two sets of ports for speakers is plenty, especially since I can hook my subwoofer to it and connect more from there. My speakers are pretty cheap but the new receiver makes the sound quality way above average. All three dials (treble, bass, volume) are very useful. For under $50, I’m very impressed how compact they managed to make it, along with the great build quality and minimal (but useful and carefully selected) number of ports on the back. Well done. ... show more

    • great little amp. does the job nicely
i got this to replace the final stage on the sony amp that blew it's left side. the sony still works as a preamp and switcher for the turntable, tv and music streamer i have so i didn't have to redo a lot of wiring. all i had to do was run a line from the tape-out on the amp and move the speaker wires to this little guy. all my controls and remotes stayed the same. nice bonus is i now also have bluetooth. it's not as powerful as my original amp and you can't drive it as hard; ive a feeling if you do, something will blow as the components are rather small. it happened on another, similarly built amp. the sound quality is adequate, esp in this age of earbuds. my wife doesn't notice but i can definately tell there is a midrange bias, even with the tone controls. still, it's good for it's size. one thing i really like is the bluetooth addition. the sound quality is good and there is very little spurious noise. it is a preferential connection so it will override anything coming in from the AUX inputs. i wish there was a button to switch but as is, just turning off the bluetooth on your phone will cause it to automatically switch back. overall, it's a good little unit. i wish it were closer to a $60 price point but build quality seems good and sound quality overall is great for this little guy. i'll probably buy another one to use as a portable outdoor entertainment like another reviewer did. ... show more

    • Best budget audio receiver I could ask for
I've bought multiple fosi audio products at this point. Love every single one of them. The one in my livingroom connects to my PC, Phone, TV over bluetooth and is super easy to use. I also have my turntable wired directly to the device and it's fantastic. The sound quality is fantastic out of my Jamo tower speakers, the Bluetooth latency is negligible. I have a second receiver in my bedroom connected to some more tower speakers and that device is connected to the same PC, a projector that is pointed towards the ceiling, and my phone. Everything works out of the box. One thing I will say is that if you want to use multiple of these they all show up as the same name. There is no way to configure the device but renaming on the devices themselves makes it easy to select the right one. I can even make my PC output to both receivers and with a little latency control I can have them in sync and my whole house is filled with music. Love these! ... show more

    • Works great
Works great, audio sounds good, no issues pairing or reconnecting with iPhone or turntable. Driving 4 Yamaha 6” ceiling speakers. Range is okay but obstacles can definitely block the signal.
