    • I can't say enough about this!
First off let me say that I have also purchased a Fosi Class AB amplifier and I like very much. Having seen a youtube video showing the difference in the sine waves between a class AB amp and a class D amp, I understood why there is inherently more distortion with class D amps. That being said, I don't know what the electrical engineers did at Fosi but the sound produced for the price paid is nothing short of amazing! The first thing I did was hook it up to a 24 volt 5.7 amp power supply from my SMSL AD18. As compared to the shipped power supply, which is not bad, the sound really seemed to open up. The bass seems more pronounced but very taut and the trebles on the other end really opened up. Where to start... the soundstage produced by this tiny little amplifier is awesome. When hooked up to my bedroom speakers, if I lay in bed and close my eyes its very hard to tell where the speakers actually are. The details and clarity are wonderful, I heard things in some songs that I never noticed before. Also equally impressive is the channel separation. I'm not sure if its because I am used to streaming through units with their own built in bluetooth so I am asking an amp to perform two function and do them both well. The current setup is a BluDento connected by RCA cables. This unit is supposed to produce quality sound when connected by a coaxial cable or toslink optical cable but the best sound is supposed supposed to be produced when connected by the stereo analog outputs. All I can say is that there appears to be no crosstalk between channels and the sound produced is engaging and immersive. Its solid and clean from top to bottom. This is just my 2 cents and your mileage may vary but from where I stand, this is one solid little audio amplifier. No bells no whistles it just does one thing and I think it does it very well. ... show more

    • Sound is clear, substantial.

This amp makes the music listening experience wonderful. I've been streaming music over Sonos and Polk speakers throughout my home for several years now, and I'd forgotten how to enjoy listening to music. I've paired the Fosi amp V1.0B with the K5 Pro mini stereo gaming DAC.

    • Very Impressive and Enjoyable
OK, lived with it for a couple of weeks now, and am really very impressed. My background is a former budget audiophile who has been unable to set up a decent system for six years now- and decided to see what ChiFi is all about. Last system was vintage Amber Series 70 amp/Parasound preamp/NAD cd/Magnepan MMG and I'm comparing this to my memory of that. I've paired this Fosi AudioTPA3116 based integrated amp with Q Audio 3010 speakers and a Chromecast Audio. The Q Audios are small enough so that I'm unable to judge lower region bass availability, and the ChromeCast Audio means that I'm still dealing with Spotify compression, but with those caveats here we go... Very surprised at the available power and the control this had over the (small) speaker cones. Chose it because this board design appears to have more capacitors then others on Amazon, but I was used to having big cans in the Amber and was skeptical on it's high-current demand performance. At least with the small speakers I need not have worried, this sounds easy and effortless within it's smaller wattage environment. Don't sense the amp straining or playing catch-up with varied types of music. They say these things have around 90% efficiency, and it shocks me that there's this much push available from this tiny unit. If you're banging big speakers at high volume you may feel differently, but for normal/louder listening levels in a 300 sq ft room this just pours it out. Transparency and presence are very good, with believable voices and instruments that have impact and some resonance. Sound staging and imaging are also good with easily located musicians in a reasonably wide area- that area is a bit shallow though, without great depth, and the musicians sound slightly distant instead of right there in your room. The important caveat here is the Chromecast Audio limitations. I believe that these areas are particularly affected by streaming through Spotify rather than a direct connection from a disc player or lossless audio feed and my issues may well have to do with the source. The tonal quality does seem dry to me. Not harsh in any way, but vocals and stringed instruments particularly don't have the warmth that I prefer (very dry at first listen with typical improvement over time.) That being said, there's lots of detail here, and you can even hear a bit of breathing/fingering/striking. It's a more analytical approach, and really the amount of information available is extremely impressive for this price. I think this reflects the quality of the preamp that's in there, and that kinda leads to the idea that there's a very short signal path in this thing. With a really small board, no tone controls and only one input, seems to me that even though the chip is playing around with DSP in some way that I don't understand, there's a lot of 'straight wire with gain' positives here. This does not sound like an expensive high-bias AB amp with a 10 pound heat sink. Don't expect that, but this is a much better than anticipated integrated amp that is of high enough quality to allow for enjoyable critical listening and is great value! It sounds considerablly better than a typical 1980s/1990s mass market receiver, and at this price it's a ridiculous bargain. Back in the Dino days, you would pay much, much more money to get this kind of sound quality. A great entry into higher-end sonics. ... show more

    • Great Sound at a Great Price

Small size, good looks, simple functionality, and excellent sound - a great combination. The amp looks and feels solid, no issues with the build quality and craftsmanship. The inputs look nice and the potentiometer feels sturdy. I installed the amplifier for a short test with the following setup: 19 V PSU, 2x 50 W 4 ohm bookshelf speakers, RCA in from a laptop. It sounded good - audio is clear with no noticeable distortion or noise. It was able to get very loud. Currently, the mids are strong and accurate. The highs are solid and clear. Lows/bass could be a little stronger and more rounded, comparable to my old low end Pioneer Hifi amplifier. I got a reasonable volume with this setup, it was the good time to replace the old setup with a new one. The amp didn't get warm to the touch during the 30 minute listening session. I'm pretty impressed with this little amp - great price for such a class d amplifier and I recommend it. Let's hope it will stay functional for a long time. ... show more

    • The Fosi class V1.0B class D amp is REALLY nice!
I put together a simple computer controlled audio system for a Cafe styled room in an assisted living complex. It consists of an Amazon Echo Dot, the Fosi amplifier, and a pair of Dayton Audio B 652- AIR speakers. The amplifier played for hours, breaking in the speakers, and remained cool to the touch as the quality of sound continued to improve as the system mellowed. It is a solidly built device that delivers a true 50 watts per channel To a four ohm impedance load. My speakers are six ohms impedance, so the wattage will be a bit less with lower Distortion, possibly 40 watts at .2 percent distortion. In any case, the amp is really a nice sounding unit, built like a tank, and very Inexpensive. At 50 dollars cost, I don’t think it can be beat. ... show more
