Review: Small yet powerful - It works very well I'm impressed. Review: One of the best no-nonsense amps for music lovers/audiophiles with small to medium sized rooms… - I needed to gift a stereo system and I really didn’t need to think about which amp I’d pick up. It was almost a given. The Fosi, suffice to say, didn’t disappoint even when paired with speakers I originally didn’t mean to buy (I was looking for the Klipsch RP400M but couldn’t find them anywhere). And once I set the system up, the BT20A simply rose to the occasion, bad room dimensions and all. My only niggle, the volume increase is not linear. Turning up the knob doesn’t do much until about 25% up and then at 60% begins to amplify the sound exponentially. And it also does not have the resistive/expensive feel of the volume knob on the BT10A that I use as a personal desktop system ## Features - 300 Watts x2 Power Output: Provided by the TI TPA3255 chip which features an advanced feedback design and proprietary high-speed gate driver error correction. In addition to excellent audio performance, TPA3255 achieves both high power efficiency and very low power stage idle losses below 2.5W. - High Efficiency: A significant upgrade from the BT20A amplifier. There're two plug-ins NE5532 Op-Amps can be replaced by LME49720HA/MUSES02/OPA26041P/OPA2134PA/LM4562/NJM4556AD Op-Amps etc. To create a different sound quality. SNR≥108dB; THD≤0.005%. - Upgraded Bluetooth 5.0 connectivity: By pressing and holding the volume control for five seconds, the Bluetooth pair can be cleared. In addition, it has a Bluetooth memory function, so it can be easily paired the next time. It also receives an alert tone. - Sound Control: With its unique design, the BT20A Pro amplifier for home audio has a wide range of bass and treble controls. Alternatively, you can turn the treble and bass effects to a middle point to listen to the original sound without effects. - What you Get: BT20A Pro Power Amplifier x1, Bluetooth Antenna x1, Spare Volume Knob x1, 32V 5A Power Adapter x1, AC Cord x1, User Manual x1, our worry-free 24-month warranty, and friendly customer service. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07JVFY27T | | Best Sellers Rank | #3,948 in Electronics ( See Top 100 in Electronics ) #4 in Home Audio Amplifiers | | Brand | Fosi Audio | | Built-In Media | BT20A Pro Hi-Fi Amplifier, Bluetooth Antenna, 32V 5A Power Supply, Power Cord | | Customer Reviews | 4.5 out of 5 stars 2,940 Reviews | | Item Weight | 567 Grams | | Manufacturer | Fosi Audio | | Mfr Part Number | BT20A Pro | | Model Number | BT20A PRO | | Number of Items | 1 | | Unit Count | 1.0 Count | ## Product Details - **Item dimensions L x W x H:** 14.2 x 10.7 x 0.4 centimeters - **Manufacturer:** Fosi Audio - **Maximum supply voltage:** 32 Volts (DC) - **Minimum supply voltage:** 32 Volts (DC) - **Voltage:** 32 Volts ## Images ![Fosi Audio BT20A Pro 300W x2 TPA3255 Bluetooth 5.0 Home Audio Stereo 2 Channel Amplifier Receiver Mini Hi-Fi Class D Upgraded Integrated Amp for Speakers with Bass Treble Control - Image 1](https://m.media-amazon.com/images/I/61ne1lo34ML.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Small yet powerful *by V***D on 4 June 2026* It works very well I'm impressed. ### ⭐⭐⭐⭐⭐ One of the best no-nonsense amps for music lovers/audiophiles with small to medium sized rooms… *by S***E on 22 July 2024* I needed to gift a stereo system and I really didn’t need to think about which amp I’d pick up.

This can beat the amplifiers costs more than 10 times of its cost. I was not so confident to buy a class D amp as i always felt that class D amps lacks musicality. But this one made me a fan a Fosi audio. I am ordering P3 preamp now and wish to to try the ZA3 model too. Kudos to fosi audio for bringing quality products for affordable price. I am following fosi audio for new releases and their models will always have a place in my youtube channel techavmallu as reviews and ownership experience. ## Frequently Bought Together - Fosi Audio BT20A Pro Bluetooth 5.0 Amplifier, 300W x2 Wireless Amp, TPA3255 2 Channel Mini Class D Integrated Home Audio Outdoor Stereo Receiver with Bass Treble Control for Passive Speakers - Banana Plugs with Dual Set Screws,Black and Red Aluminum Shell,6 Pairs - Amazon Basics Speaker Cable, Easy Assembly, 16-Gauge, Bronze, 100 ft --- ## 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.gr/products/322368103-fosi-audio-bt20a-pro-300w-x2-tpa3255-bluetooth-5-0](https://www.desertcart.gr/products/322368103-fosi-audio-bt20a-pro-300w-x2-tpa3255-bluetooth-5-0) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-09-29*
