FiiO S15 Streaming Media Player review with Android 12 and AKM DAC performance

Description

Impressive Build and Design

Right out of the box, the FiiO S15 Streamer Network Player makes an impression with its sleek black finish and sturdy construction. Weighing in at a hefty 17.46 pounds, it feels substantial and well-built, which is something I always appreciate in high-end electronics. The 430mm standard chassis width is perfect for larger desktop audio systems, making it blend seamlessly into any setup. The 7.84-inch automotive-grade color display is a game-changer—bright, responsive, and just the right size for navigating through music apps or tweaking settings. I especially loved the dual knobs and virtual buttons, which make local operation intuitive even without the remote or app.

Audio Quality: A Standout Performer

Here’s where this device truly shines. The AKM flagship DAC combination (AK4191+AK4499EX) delivers an audio experience that feels both natural and dynamic. I tested it with a variety of genres, from classical to EDM, and its ability to enhance resolution while maintaining balanced dynamics is remarkable. Whether you’re listening to subtle acoustic tracks or bass-heavy beats, the sound remains crisp and detailed. The dual ACCUSILICON AS318-B femtosecond oscillators also deserve a shoutout, as they ensure high fidelity decoding and precise digital output. Hooking it up to my external DAC resulted in some of the cleanest sound I’ve heard in this price range.

Upsides

• Seamless integration with streaming apps: The open Android 12 OS supports major music apps like Spotify, Tidal, and Roon, making it incredibly versatile for streaming.
• Extensive connectivity options: From I2S output to HDMI ARC, this device covers everything you’d ever need for a home audio system.
• Exceptional audio performance: The combination of AKM DACs and ultra-low phase noise oscillators results in a reference-grade sound experience.
• Versatile control options: Whether using the Bluetooth remote, app-based control, or physical knobs, operating the device is a breeze.

Areas for Improvement

• Limited customer reviews: With just 8 ratings and a 2.8-star average, it’s hard to gauge long-term reliability.
• Potentially overwhelming for beginners: The sheer number of features and settings may intimidate those who are not tech-savvy.
• Weight and size: While sturdy, the 17.46-pound build and large dimensions might not suit smaller spaces or portable setups.

Performance Across Applications

I pushed this device through its paces, experimenting with multiple input and output methods. The Bluetooth network streaming is reliable, and the DLNA support worked flawlessly with my NAS system. I also appreciated the Roon Ready compatibility—it made integrating the player into my existing setup effortless. The HDMI ARC output is a standout feature for anyone using this as part of a home theater system, offering seamless audio transfer without lag. However, the XLR balanced line output was my favorite—it delivered the cleanest signals when connected to my studio monitors.

Product Rivals

In its price range, the FiiO S15 competes with names like Cambridge Audio CXN V2 and Bluesound Node X. The CXN V2 offers excellent sound quality and a similarly sleek design but lacks the expansive connectivity options of the S15. On the other hand, the Bluesound Node X excels in its wireless capabilities but doesn’t quite match the detailed audio performance of the S15’s AKM DAC setup. If you’re prioritizing connectivity and high-resolution output, the S15 edges out its competitors in this regard, though it falls behind in terms of user-friendly setup for beginners.

Smart Spending

Given its feature set, this product offers strong value for the investment. While not the most budget-friendly option on the market, its robust build quality, premium audio performance, and extensive compatibility with streaming services more than justify the price. If you’re serious about sound quality and need a device that integrates effortlessly into a high-end audio system, this unit delivers. Sure, there are cheaper options out there, but few come close to offering the same level of versatility and performance.
