Fosi Audio V1.0B 2 Channel Stereo Audio Amplifier Receiver Mini Hi-Fi Class D Integrated Amp for Speakers 50W x 2 + 19V UK 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 yearsIn 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 issuesReally happy so far.

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++++++

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.

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.

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.

Fantastic little amp, great power, hi-fi quality, clear audio and great value!

Like* Compact size* Banana plugs* Build QualityDislike* Audio qualityReviewThe audio quality leaves a lot to be desired. It's not 'terrible', but merely passable. If you have any halfway decent speakers then this would be a waste of both your money and your speakers. I made that mistake, so hopefully you won't have to.On my unit, on lower volumes it favours the left channel over the right. If I wasn't using this as a computer amp for some bookshelf speakers, this alone would have caused me to send it back. Fortunately I don't need to change the volume, as I do this via my computer instead.The actual build quality is quite good. It's a metal case, and has decent banana plug connections. It's just a shame the audio quality simply isn't that good.However, I'm fortunate enough to have been subject to decent hifi components. Perhaps I'm just being snobby, and for the vast majority of people, they will wonder what I'm talking about, and it sounds perfectly fine.As an everyday desktop amp for desktop speakers it's perfectly fine for the vast majority of everyday people. Myself included if I'm honest. I simply expected more based on all the other reviews.I also wish Amazon allowed you do half star reviews. As I feel 3 is too low, and 4 is way too high.3.5 stars is about right. At the price point, for what it is, and that it's basically no better than a set of Logitech powered speakers, then I really can't give it any higher.

Item was essentially dead on arrival. The amp only worked when you forcefully held the power cable in at a straight angle. Due to that, when I did eventually manage to get power, the audio that came out of my speakers was insanely grainy and terrible quality. I’ll be refunding it and getting an amp from a more reputable company.
