Deze versterker overtrof mijn verwachtingen. 2 passieve luidsprekers en een subwoofer aangesloten. Echt prima geluid. Ongetwijfeld bestaan er betere versterkers maar dan betaal je een bak geld voor iets beter geluid. Enige nadeel dat ik kan verzinnen is dat je maar 1 invoerkanaal heb. Ik heb er maar 1 nodig, dus voor mij geen issue. Onverwacht goed!

Looked for a small replacement amplifier, to get some more space on my desk, as Corona keeps us home bound. Read some of the reviews and was very sceptic. However the sound is pretty solid and detailed, which I didn't expected from such cheap device.I do miss some details, compared to some high-end units with a class-D, but to be honest, that difference doesn't sound worthy 600 Euro.

This is a little powerhouse of an amp. Superb build quality, nice and solid packaging, easy to connect and handle.Attached 2x 200 Watt speakers and to protect the neighbours, I'm just opening it up halfway... what a sound/power!Bluetooth is connecting easy and fast; range is, even in open sight, a bit disappointing.

We hebben deze versterker voor de serre in gebruik met Power Dynamics BD50B speakers en echt top geluid. Meer dan voldoende volume en de sound is krachtig en voelbaar laag.We hebben de speakers 2,50 hoog hangen en nog is het geluid top.

Great powerfull warm sound. Bluetooth connection connects perfect. Well done Fosi Audio with this bestseller BT20A 👍👍👍👍👍

Werkt goed.

Doet het goed. Maakt wat onrustig gemurmel als het geluid erg zacht (of uit) is.

I bought this little amp for my daughter to allow her to stream and connect a few stand alone speakers. I already purchased one earlier for my son but didn't realize that he has a more recent version (2020 I believe) that has an update in the bluetooth receiver.The 2nd one (for daughter) didn't yet have this update and every 90 seconds, the signal would dip just a bit of a second and come back on. But clearly, this was annoying. After exchanging video's and descriptions with the Fosi customer department, they sent me a new circuit board that I replaced with the old one. I saw that indeed, the bluetooth circuit looked different. This new version works perfect. Based on quality of the product, I would have given it 5 stars. But with this glitch, I settle for 3.

最近のPCオーディオの音質向上は驚きです。中華ブランドの技術はすごいですね。コレはオススメです。

Orkade utan problem driva mina högtalare ute på altanen.Kanon!Bluetooth och line-in fungerade perfekt.

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

I’ve had it for a year and no problems, great sound

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.
