Small is beautiful!
I only recently got interested in HiFis. After spending a decent chunk on a system - all new I decided to create (or rather cobble together) one buy scouring the internet. Got these AED 259 - they have a special running, used floor standing Mission M73i speakers, a very old and used Sonos Connect ZP 90 (only streamer not amp). The used stuff off Dubizzle and the new amp from Amazon. Including wires (from Pult in Dubai) the whole thing set me back by AED 1134.00 Worth it. This amp is great. Initially felt a bit underpowered but then I turned up the treble and bass to almost max. Fixed that. With the ZP90s connected to this I get to hear beautiful music from Qobuz and Spotify on the M73is. I recommend not using the Bluetooth connection if possible- sound quality not that good (as Wi-Fi) and if your is not set to silent mode then even the keyboard clicks can be heard on the speakers. Overall: an outstanding purchase. Will post pictures of the connections soon. April 2023

Tiny amp, big sound. Bluetooth volume controllable.
This is a very good amp. No buzzing or issues. Loud enough for parties and quiet enough for background music. Bluetooth feature is good, and you can increase and decrease volume from your phone once connected. Set the volume on loudest you want before any distortion, then crank the volume back a tiny bit, and then use your phone to manage the volume. I would buy again if I needed an amp.

Works perfectly! I used this to fire up a pair of outdoor speakers that came with our house, and it’s been flawless. Super easy to connect via Bluetooth, and the sound quality is great — clear, strong, and consistent. I’ve left it on pretty much all the time, and it’s been running solid for about 8 months with no issues at all. For the price, this little amp delivers big performance. Highly recommend.

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 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.

ich habe diesen kleinen Verstärker für meinen Camper bestellt, um auch beim Camping in guter Qualität Musik hören zu können (zusammen mit zwei kleinen Elac Boxen) selbst über Bluetooth ist der Klang recht gut und mit den Bass- und Höhenreglern kann man noch etwas optimieren. ich betreibe den Verstärker direkt mit 12V aus der Bordbatterie, so kann ich zwar die Leistungsfähigkeit nicht voll ausnutzen, aber die erzielbare Lautstärke genügt mir. im Grunde sind es vier Dinge, die mich bewogen haben, diese Verstärker zu kaufen: - er macht einen fertigen Eindruck und ist wirklich sauber verarbeitet -der Klang ist zu jeder zeit sauber, schnell und sehr gut auflösend, ohne Spitz oder nervig zu sein -das Ding ist so winzig, das passt auch in das kleinste Wohnmobil - der Wirkungsgrad ist fantastisch, d.h. ich kann ewig lang Musik hören, ohne dass meine Batterie schlapp wird. ich bin, wie man wohl deutlich hört, sehr zufrieden und würde mir das Gerät jederzeit wieder kaufen und auch Freunden empfehlen. Nachtrag: ich habe das Teil auch mal zu Hause über das mitgelieferte Netzteil an meine Lautsprecher angeschlossen (Hörner) Hier vermag der Zwerg ein wahres Inferno zu beschwören und steht zumindest klanglich meinem Nubert Amps in nichts nach. für diesen Preis habe ich noch nichts Besseres gehört Es gibt auch noch zwei Geschwister dieses Gerätes, den BT10 a ( den habe ich auch) klanglich fast genauso gut, halbe Leistung und noch kleiner und günstiger. und den BT20pro, den ich allerdings noch nicht gehört habe
