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. Review: Fantastic little amplifier. - 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. ## Features - Fosi Audio V1.0B mini stereo amplifier includes highly efficient, fully integrated, digital, class D audio amplifier ICs based on NEW amplifier technology, supporting a supply voltage range from 12 V to 24 V, allowing it to be used across home and professional audio applications - V1.0B 2-channel class D amplifier adopts 2PCS Texas Instruments TPA3116D2 chip.

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. ## Frequently Bought Together - Fosi Audio V1.0B 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 - Fosi Audio K5 Pro Gaming DAC Headphone Amplifier Mini Hi-Fi Stereo Digital-to-Analog Audio Converter USB Type C/Optical/Coaxial to RCA/3.5MM AUX for PS5/PC/MAC/Computer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.il/products/43772157-v1-0b](https://www.desertcart.co.il/products/43772157-v1-0b) --- *Product available on Desertcart Israel* *Store origin: IL* *Last updated: 2026-06-23*
