1. The Evolution of a Legend: BT20A Pro

The Fosi Audio BT20A Pro is the high-performance successor to the world-renowned BT20A.

It is the definitive choice for audiophiles who want a compact yet monstrously powerful stereo amplifier.

2. Key Features & Pro-Grade Upgrades

Unmatched Power with TPA3255

• Massive 300W x2 Output: By upgrading to the flagship Texas Instruments TPA3255 chip, the BT20A Pro delivers a staggering 300W x2 (@4Ω). It effortlessly drives large floor-standing speakers with authority and precision.

• Premium Audio Components: Featuring high-end inductors and capacitors, the Pro version provides a much lower noise floor and higher signal-to-noise ratio than standard mini amps.

Designed for Audiophile Customization

• Swappable Op-Amps: The BT20A Pro features internal DIP8 sockets, allowing you to swap the stock NE5532 Op-Amps for high-end alternatives (like Muses02 or OPA2134) to "roll" your own signature sound.

• Linear Tone Control: The Bass and Treble knobs now feature a center-detent, allowing you to easily reset to a "Flat" response for pure, uncolored sound.

Refined Connectivity

• Advanced Bluetooth 5.0: Enjoy stable wireless streaming with a wide range. The BT20A Pro also includes an all-new Bluetooth reset button—simply long-press the volume knob to clear all pairings instantly.
