Fosi Audio DA2120C Bluetooth 5.0 Stereo Amplifier Review High-Performance and Versatile Audio Solution

Description

An Introduction to the Fosi Audio DA2120C Bluetooth Hi-Fi DAC Amplifier

I recently had the chance to try out the Fosi Audio DA2120C 240W Bluetooth 5.0 Stereo Audio Hi-Fi DAC Amplifier, and I must say, it left quite an impression. This 2.1 channel amplifier seemed like a great addition to my home audio setup, offering a mix of modern connectivity options and solid performance. With features like Bluetooth 5.0, multiple input modes, and EQ control, it promised versatility and high-quality sound—and I was eager to test those claims. Spoiler alert: there’s a lot to love here, but it’s not without its quirks.

Design and Build Quality

The first thing that caught my eye was the compact aluminum enclosure. It’s sleek, sturdy, and has a premium feel. Weighing just over 3 pounds and measuring 7 x 5 x 1.5 inches, it’s small enough to fit on a desk or shelf without taking up too much space. The bright digital LED display is clear and easy to read, even from across the room, which is a bonus if you’re adjusting settings frequently. Honestly, the design reminded me of some high-end amplifiers priced significantly higher, so it’s a win in the aesthetics department.

However, while the build quality feels solid, the remote control included in the package felt a bit plasticky and lightweight. It gets the job done, but it doesn’t exactly scream luxury. I also noticed the Bluetooth antenna sticks out at an angle, which some might find slightly awkward if they’re particular about symmetry in their setup.

Performance and Sound Quality

This device isn’t just about looks—it backs it up with 120 watts x 2 @ 4 ohms of power output. I tested it with a pair of bookshelf speakers and a powered subwoofer, and the sound was both acoustically accurate and distortion-free. The Texas Instruments TAS5352A chip really shines here, ensuring low harmonic distortion and integrated noise. The result? Crisp highs, punchy lows, and a balanced midrange that made everything from jazz to electronic music sound fantastic.

The EQ control was another standout feature. Tweaking the bass and treble levels was intuitive, and it made a significant difference when switching between genres or adjusting for different room acoustics. That said, if you’re an absolute audiophile, you might notice that the sound lacks the warmth of some pricier tube amplifiers. For most casual listeners, though, the sound quality will be more than adequate.

Versatile Connectivity Options

One of the amplifier’s biggest strengths is its wide array of input modes. It supports Bluetooth, RCA, PC-USB, Coaxial, and Optical inputs, making it compatible with virtually any device. I paired it with my phone via Bluetooth 5.0, and the connection was both stable and fast, with no noticeable lag. The 6dBi high-gain antenna ensures a range of up to 65 feet, which meant I could move around my apartment without worrying about losing the signal. Streaming music wirelessly was seamless, and the audio quality didn’t take a noticeable hit, thanks to aptX support.

I also tested the optical input with my TV, and it worked flawlessly, delivering clear and synchronized sound. However, I found the lack of HDMI input slightly limiting for certain setups, especially if you’re planning to use it as part of a home theater system.

Key Benefits

• Compact and sturdy aluminum design that fits seamlessly into any setup.
• 120W x 2 power output capable of driving most passive speakers and subwoofers.
• Multiple input options, including Bluetooth, RCA, Optical, and more.
• Bluetooth 5.0 with aptX for high-quality wireless streaming.
• Intuitive EQ controls for fine-tuning your sound preferences.

Areas for Improvement

• The remote control feels cheap and could use an upgrade in build quality.
• No HDMI input for those looking to integrate it into a home theater system.
• While the sound is clear and distortion-free, it may lack the warmth some audiophiles prefer.

Competitive Options

It’s hard to talk about audio equipment without comparing it to other players in the market. The Fosi Audio DA2120C goes head-to-head with brands like SMSL and Topping, both of which are known for their compact and feature-rich amplifiers. Compared to the SMSL AD18, for instance, the Fosi takes the lead in Bluetooth range and stability, thanks to its 6dBi antenna. However, the SMSL amplifier offers slightly better sound detail and a more premium remote control.

On the flip side, Topping’s amplifiers often deliver superior DAC performance, but they typically come at a higher price. What gives the DA2120C an edge is its versatility and affordability, making it a great choice for beginners or those looking for a solid secondary amplifier.

True Value

From my experience, this amplifier offers impressive value for money. Considering its robust feature set, solid performance, and wide connectivity options, it’s hard to find a comparable product at this price point. While it’s not without its flaws, the overall package feels like a smart investment for anyone looking to enhance their home audio experience without breaking the bank.

If you’re in the market for a versatile and compact amplifier that delivers reliable performance and modern features, this one is worth considering. Just be prepared to live with a few compromises, like the basic remote and lack of HDMI input. But for everyday use, it’s a powerhouse that punches well above its weight.
