Fosi Audio V1.0G 2 Channel Amplifier Stereo Audio Amp Mini Hi-Fi Class D Integrated TPA3116 Amp for Home Speakers 50W x 2 with 19V 4.74A Power Supply

I have had an old set of Dell PC Speakers (2 speakers plus a sub-woofer) for many many years. They were quite well made and had an adequate sound (volume and quality) from my computer - mainly listening to Spotify. However they stated to fail with increasing noise, static and fading volume - it may be just a dirty volume control but I was not sure so I had been looking for a replacement for some time, but nothing really looked like what I wanted - everything these days looks quite cheap and plasticy. However I also had a pair of Wharfdale Diamond 2 speakers from my old (no longer used) stereo system. These are actually relatively small but high quality speakers so I decided that a better strategy might be to deploy these speakers with a (physically) small amplifier and came across this Fosi device. I left this in my basket for a long time as well but finally got it on an Amazon discount week making it much more reasonably priced. I was not sure what to expect as I had used the speakers before with a traditional large Pioneer traditional (and large) stereo amplifier. This device is tiny - much smaller than I expected - the power brick is about twice the size of the amplifier! The photos show that the connections at the rear fill the panel. I also bought some banana plugs for the speaker cable (some quality QED flat twin and 3.5mm jack to phono cable and connected it all together. I really am impressed with the quality of the sound output with these speakers. I have had the volume at the maximum setting and it was really clean and clear, with a decent frequency range (using the Realtek graphic equalizer application) and minimal distortion, so I am pleased with the outcome and it reuses my speakers that had been in the loft for years In terms of the amplifier, it doesn't get hot even when running at high-output for long periods of time. It's quite well made - a reasonable level of perceived quality. I had one trivial issue that the volume knob fell off but it just needed the grub screw tightening a little more. I think the the power switch seems a little lightweight and could have been a little more robust looking but these are minor nitpicking issues Really happy so far.

Have recently refreshed my main sound system which was 10+ years old and lacking modern features such as optical input for TV sound, Bluetooth, and unable to play FLAC files. So what to do with my now upgraded & replaced Wharfedale Diamond 9 speakers. After a few hours research I bought this, hooked it up to my PC and the speakers, replacing some basic Creative mini-speakers. Even found just enough old Chord Carnival Silverscreen speaker cable at the bottom of a drawer. Pound for Pound this has to be the best £40 I have ever spent on audio equipment. The sound is amazing coming from a basic £300 computer. The mike on my phone really does not do it justice. Need to get them up to screen level ASAP though

I was surprised at the small size, I was expecting something slightly bigger, the sound is clear and has good bass/mids/treble. It's alarmingly powerful, I have tested it through a set of vintage Warfedales as well as some more modern wharfedales and a few other sets of speakers. My reason for buying it was because i needed an amp to play those speakers I mentioned as previously I was sending a signal directly to them from an audio interface for reference, in my home studio. I am very satisfied with this little amp. Well worth the price I paid.

Got this to replace an old hi-fi separates amp used to handle the sound on one of our computers. Perfect, sound is excellent and the desk now has more space on it. Ideal for the user as it's dead simple to use.

Professional quality - Bought one to drive my old Yamaha NS10 studio monitors, very good quality, no hums or hisses, punchy, loud enough, very well made all metal, low power consumption, power supply, volume knob, switch and connectors all solidly made, does not even get warm. I would not hesitate to buy another one if needed. AAAAA++++++

Righthand channel faded after a few days of use. I'm reasonably sure that I was unlucky with the one I purchased; this is not a usual outcome. Returned it, not easy. QR codes very confusing.

Excellent little amp. Am using it to drive a couple of old Jamo Sonic speakers (long term power: 50W, short term power, 105W, 8Ω impedance) via an audio interface attached to my laptop. Bought a couple of banana connectors to make connecting the cables easier, but connecting bare wire to the binding posts on the amp unit actually turned out to be easier than trying to get the screws to fit in the connectors. I had wondered whether the amp would have enough ooomph to get sufficient loudness out of the speakers - happy to report that it got louder than I'd dare listen to music at well before reaching maximum volume. No noticeable distortion within normal listening range. If you're only going to be using one input then it's a no-brainer, especially for £40.

Bought this to power a Dayton BST-1 bass shaker for a simracing setup, it's crazy to me that the nobsound mini which most people use for this is almost the same cost as this, the quality of this is leagues ahead of the nobsound and looks and feels beautiful and minimal to boot. I guess the nobsound is a bit smaller if you're trying to fit it onto a rig, but I preferred to have this on my desk and I love its aesthetics. Has been very reliable so far, I intend to add 2 TT25 shakers wired in parallel to the spare channel, which I would be more hesitant to do on the nobsound.

I’ve been using this little amp for about 2 years now and it’s fantastic. Great sound for the money, especially when setup properly. It was on my desk with monitors at ear level and the sound was phenomenal. Now they power the bookshelf speakers with audio from my turntable and it easily fills the house with plenty of range left on the knob. I’ll likely be getting another Fosi amp to replace this one so I can put this one at my desk. Highly recommend.

El equipo es de buena calidad. Tiene un sonido limpio, la música se escucha genial y sin ningún ruido de fondo, con un completo silencio en vacío. En mi caso, con altavoces de 6 ohmios, tiene potencia de sobra para un salón de 20 m2, para mí es suficiente no pasar el potenciómetro mas o menos del primer cuarto de su recorrido. La verdad, me ha sorprendido, los amplificadores tipo D tienen mala prensa entre algunos audiófilos, pero a mí, me ha parecido que tiene un sonido muy agradable. Muy buena relación calidad precio, por poner una pega, no parece tener protección antipop y si lo dejas encendido y lo activas directamente desde el interruptor de una regleta, por ejemplo, puedes escuchar ese temido pop que podría llegar a dañar tus altavoces.

Bought for connecting a DAC (Focusrite 2i2) to studio motor speakers. The unit is delivered including a power brick with the correct EU plug without me needing to specify when bought. Solidly packaged. Metal housing, feels like a solid and heavy build. The volume knob has a satisfying resistance when turned. Sound quality is as expected, enough juice to drive my 8 ohm speakers without interference or lack of power. To me the sound feels neutral and balanced without extremes either in bass or high frequencies.

Piccolo ed ottimo amplificatore con il noto e ben suonante chip 3116. Realizzazione ottima come materiali e finiture. L'amplificatore viene fornito di alimentatore, cosa non scontata, funziona benissimo senza il minimo rumore o ronzio. L'unico piccolo difetto sono i connettori per i cavi di potenza, piccoli e scomodi, superato prendendo le banane per cavi di Amazon Basic, veramente ottime.

C'est le deuxième ampli Chinois classe D que j'achète, ayant été conquis par un modèle d'une catégorie supérieure bien que ce petit Fosi Audio ne démérite pas non plus. On peut se demander à juste titre si ces nouveaux amplis Chinois ne rendent pas obsolète les amplis HIFI de classe AB traditionnels d'entrée de gamme car ce Fosi Audio offre un son excellent qui surprend vu la taille de l'appareil avec son transformateur de 19V. La course du volume est régulière, progressive et équilibrée et on restera en-deçà de 10h la plupart du temps même avec des enceintes de rendement faible. Scène sonore, pureté des timbres, clarté et dynamisme, à l'écoute ce mini-ampli ne cesse de nous surprendre par ses réelles qualités acoustiques. La finition est parfaite, pas de bruit parasite, pas de souffle, pas de ploc à l'allumage, ne chauffe pas et ce qui est le plus incroyable, sa consommation électrique ! Si on reste en-deçà de 12h, avec des enceintes de bon rendement, on aura déjà pas mal de puissance pour une consommation électrique qui va osciller entre 1.4w et 2.8w ! A plein volume on arrive péniblement à 3.5w ! En écoute normale on sera donc à 1.4w (volume à 9h), autant dire que c'est un avantage non négligeable, voire devenu très recherché ! Avec le volume à fond, on entend aucune distorsion ce qui est surprenant, cela dit sa puissance reste limitée mais à mon sens suffisante si on le branche sur des enceintes ayant un bon rendement. Par contre, il faudra privilégier des fiches bananes si on veut utiliser du câble de 2.5mm, les borniers n'acceptent du câble que jusqu'à 1.5mm apparemment (ce qui n'est pas un problème). Le boîtier étant léger, il a aussi tendance à basculer si on utilise des raccordements arrières trop qualitatifs (lourds). A mon sens ces nouveaux petits amplis Chinois en classe D rendent désuets les amplis HIFI classiques des grandes marques d'entrée de gamme (pour le moins) sauf si on recherche plusieurs entrées, des réglages de tonalité, une balance et une télécommande. Chacun pourra trouver une utilisation à ce petit Fosi, mais pour moi c'est l'ampli idéal à portée de main à côté d'un ordinateur et branché en sortie d'un DAC. Il pourra être utile aussi dans une seconde pièce mais l'absence de télécommande le rend moins intéressant pour regarder les films qui demandent souvent de corriger le volume pendant le visionnage. Je ne vois aucun défaut à ce petit ampli, le prix est attractif et son look minimaliste trouvera facilement sa place sur tout bureau ou étagère. Fortement recommandé. En espérant que mon commentaire vous sera utile.
