Fosi Audio BT20A Bluetooth 5.0 Stereo Audio 2 Channel Amplifier Receiver Mini Hi-Fi Class D Integrated Amp 2.0 CH for Home Speakers 100W x 2 with Bass and Treble Control TPA3116 (with Power Supply)

I have been using this amplifier for a month now. It is working without any issues. The build quality of the amp as well as the adapter is very good. Looks tiny besides my old amp. My Old amp stopped working so am using this amplifier as an temporary alternative to power a set of Solidaire SS100 bookshelf speakers with a 12-inch woofer, a 4-inch midrange, and a 1-inch horn tweeter with impedance of 8 Ohms. Bluetooth range is also good. Comparable to my existing Logitech Bluetooth adapters. I have noticed it does not get warm on long usage when listening at acceptable volumes at home. The audio quality is flat and commendable in the Fosi amp, but I seem to miss the warmth my old Solidaire AS1200D amp provided. So, I tend to boost the lows and mids from the equalizer to get the desired effects. My decision on buying this over Aimyia amp was swayed because FOSI provide a warranty on their product, but Aimyia brand amps have no such mention in their listings.

Too tiny, infact the provided adapter brick is larger. Felt little warm after couple of hours of usage. Hopefully it will last for years to come. Have hooked my LG FB162 System speakers and the sound coming out is good. Even at low volume can get clarity. Bluetooth works like charm even when I take the source device in a different room still sound doesn't distort. Wish they have provided a remote or an app to control Bass and Treble.

Its pretty good in sound quality and works well. I don't understand the part of loud noise from speaker for starting and switching off the device. Otherwise build quality, sound quality, packaging everything is very good.

Nice music system

Very good sound clarity and deep bass

Works wonderfully for my old Sony AZ2D system. The original Sony touch panel was defunct and this Fosi module has brought my amazing speakers back to life. The Bluetooth is superb. No pairing, no “sleep mode” just leave it on and connect anytime without a fuss. Compact, solid metal construction, monochrome looks, and a vintage mechanical flip-switch for powering it in and off.

Does the job perfectly

So far working well👍

高品質なサウンドが楽しめて喜んでいます。テレビとは有線で、スマホとはBluetoothで接続。Bluetoothで繋ぐとテレビの音は消音されるので、外部入力よりBluetoothを優先します。 シンプルで小型なのにパワフルで喜んでいます。

Mój amplituner Onkyo zajmował miejsce w moim minimalistycznie urządzonym salonie , dodatkowo nie posiada bluetooth , więc zakupiłem Fosi Audio , i.... Nie jestem melomanem i pewnie dla tego :-) nie słyszę różnicy między tymi wzmacniaczami , więc polecam wam też bo większość z was tak jak ja jej nie usłyszy

Hands down this is one of my favorite amps to use. From the compact design, east of use, and power. It certainly offers a lot of value. The Bluetooth connects consistently each and every time, something that I often found a challenge with similar products. The audio quality is fantastic out of a small package. Whatever I throw at it, it just handles it. Be it my customer built enclosures or my reference Klipsch speakers. The connectively makes it easy to get up and running in no time without any hassle. Highly recommend for anyone wanting to add Bluetooth functionally in there space or wanted a tiny amp for some bookshelf speakers. This is the one!
