Powering dali tower speakers in a dolby atmos setup while avr is powering up the rest of the speakers. Noticeable improvement in clarity and bass of the towers. I wanted to reduce the load on my denon AVR and so far i am happy with my purchase. ### ⭐⭐⭐⭐ Awesome go for it *by M***H on 9 October 2025* Good i am using this as an dual subwoofer setup for denon x1800h av receiver using this for 2 weeks no issues working good, no distortion sound/humming issue ### ⭐⭐⭐⭐ Recommend for people to start their audiophile journey *by R***P on 29 April 2025* the v3 is really good for the base. It is also ideal if Fosi comes up with a hybrid amp with tubes for the Mids and Highs or another tube amp with the same gain as v3. The Volume knob is smooth, but a bit too smooth, and I think it would be best to have the volume marker in flourescent for better visibility. The binding posts could have been better organized. Overall a good class D amp. ## Frequently Bought Together - Fosi Audio V3 Stereo Amplifier Home Audio 300 Watts x2 Power TPA3255 Class D Mini Speaker Amp 2 Channel Audio Component for Passive Bookshelf Tower Speakers Desktop Home Theater with 48V Power Supply - Fosi Audio Replaceable Control Knob Orange Controller for V3 Amplifier Stereo Amplifier Home Audio - WiiM Mini AirPlay 2 Wireless Audio Streamer, Multiroom Stereo, Preamplifier, Works with Alexa and Siri Voice Assistants, Stream Hi-Res Audio from Spotify, Amazon Music and More --- ## 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.vu/products/639557545-fosi-audio-v3-300-watts-x2-power-tpa3255-mini-amp](https://www.desertcart.vu/products/639557545-fosi-audio-v3-300-watts-x2-power-tpa3255-mini-amp) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-08*
