SMSL A50 PRO HiFi Power Amplifier Review Bluetooth 5.0 and 2.1-Channel Features

Description

Design and Build Quality

The S.M.S.L A50 PRO HiFi Power Amplifier immediately stands out with its sleek, compact design. Its minimalistic aluminum casing not only feels durable but also adds a modern touch to any audio setup. I couldn’t help but appreciate how lightweight it is, weighing just 2.43 pounds—perfect for moving it between rooms or rearranging setups. The 12.68 x 7.8 x 2.87-inch dimensions mean it doesn’t hog space, making it ideal for those working with limited areas like desks or small entertainment centers. The buttons and remote are intuitive and responsive, though I did notice that the remote’s plastic felt a bit flimsy for a product in this range. Still, it’s a minor issue in an otherwise well-thought-out design.

Performance and Audio Quality

Using this amplifier daily, I was genuinely impressed with its high-fidelity performance. The Infineon MA12070P chip ensures clear, distortion-free sound even at higher volumes. It produces 100 watts of passive bass output power, which effortlessly drives my bookshelf speakers and a passive subwoofer. Adjusting the subwoofer’s volume (from S00 to S99) gave me precise control over the bass, something I found incredibly useful while switching between music genres or watching movies. Its ten adjustable crossover frequency points for high-pass and low-pass filters allowed me to fine-tune it for different speakers, creating a true 2.1-channel audio experience. That said, I found the bass adjustments could be a bit more intuitive for someone less familiar with audio systems.

Versatility and Connectivity

One of the key benefits of this amplifier is its wide range of connectivity options. Whether I wanted to connect my TV using the HDMI ARC port, stream music via Bluetooth 5.0, or plug in older devices through the AUX input, the A50 PRO handled it all seamlessly. The USB-C port is a welcome addition, especially since it’s driver-free, making it plug-and-play for most systems. I also tested the optical input, which worked flawlessly with my gaming console. However, while the variety of inputs is fantastic, I wish the Bluetooth range were slightly better—it started losing connection if I moved my phone to another room.

Multiple EQ Presets and Customization

The multiple EQ presets on this amplifier are a game changer for anyone who enjoys experimenting with different audio settings. With customizable bass and treble adjustments ranging ±9 levels, I could easily adapt it to match my music preferences, whether I was listening to classical, rock, or EDM. What stood out was how well it retained audio clarity even when I cranked up the bass. Having these options made the listening experience truly immersive, though I did notice that switching between presets wasn’t as seamless as I’d hoped—it required a bit of trial-and-error to find the perfect setting.

Good Aspects

• Powerful audio output: Handles a variety of speakers with ease and delivers clean sound.
• Compact and robust build: Fits into tight spaces while maintaining a premium look.
• Versatile connectivity: Works with nearly all audio sources, from TVs to smartphones.
• Customizable EQ settings: Tailors the sound profile to suit different genres and preferences.
• Adjustable subwoofer volume: Perfect for creating a balanced 2.1-channel system.

Caveats

• Remote quality: The remote feels a bit cheap compared to the rest of the product.
• Bluetooth range limitations: Works well within the same room, but struggles at a distance.
• EQ preset navigation: Could be simplified for users unfamiliar with advanced audio setups.

Competitive Options

In comparison to other amplifiers in this category, the A50 PRO holds its own. Against the Fosi Audio BT20A, for instance, the A50 PRO offers more precise subwoofer controls and better EQ customization. However, the BT20A has a slightly better Bluetooth range. On the other hand, while the Yamaha WXA-50 might deliver slightly richer sound, it doesn’t come close to the compact size and affordability of the A50 PRO. What really sets the A50 PRO apart is its HDMI ARC support, which is rare in similar products at this price point.

Price to Quality Ratio

In terms of value for money, the A50 PRO delivers a well-rounded package. Its combination of connectivity, customization options, and powerful audio output is hard to beat. While it isn’t the cheapest amplifier out there, every feature feels purposeful, ensuring that you get the most out of your investment. Whether you’re setting up a home theater or upgrading your music system, this product strikes a balance between performance and cost-efficiency. That being said, audiophiles looking for absolute perfection might find themselves leaning toward pricier alternatives for those marginal gains in sound quality.
