I recently decided it was time to upgrade my small home audio setup, specifically needing something compact yet powerful enough to drive my bookshelf speakers properly. After a bit of searching on US online platforms, I landed on the Fosi Audio BL20A Bluetooth TPA3116 Sound Power Amplifier 2.1CH 100W Mini HiFi Class D Amp Bass Treble With U-Disk Remote Control. The promise of a Class D amplifier with dedicated bass and treble controls in such a small footprint really caught my attention, and I was eager to see if it could deliver clean power.

Setting this device up was remarkably straightforward. Pairing via Bluetooth was instantaneous, which is always a huge plus when you just want to start listening right away. What I immediately noticed, even at moderate volumes, was the clarity this little machine produces.

The TPA3116 chip seems to be doing its job perfectly, offering crisp highs and surprisingly tight mid-range. Furthermore, having dedicated bass and treble knobs is a feature I didn't realize I was missing; I could dial in the perfect sound signature for different types of music without fiddling with external EQs. The inclusion of a U-Disk input is an unexpected bonus, allowing me to play lossless files directly, bypassing my phone entirely for the highest fidelity listening sessions.

I’ve been thoroughly impressed with the performance, especially considering its size. It powers my setup robustly enough for casual listening without any signs of overheating or distortion, even when I pushed the volume slightly higher than usual. The included remote control is handy for quick adjustments when I’m across the room, making the entire user experience feel premium despite the modest price point of this amplifier.

I haven't found any serious drawbacks yet, and since there are no other user reviews available for comparison, I can confidently say that for my needs, this product exceeded expectations.

If you are in the market for a small, feature-rich amplifier that offers substantial power and detailed control over your sound profile—especially if you need 2.1 channel capability for a subwoofer—this is a fantastic option. It’s perfect for desktop setups, small living rooms, or even as a garage/workshop amp. Anyone looking for an audiophile experience without breaking the bank should seriously consider the Fosi Audio BL20A.

Seriously, skip the generic Bluetooth speakers and invest in this power unit; you won't regret picking up the Fosi Audio BL20A.
