FiiO S15 Streaming Media Player Review Android 12 AKM DAC Features Explained

Description

Design and Build Quality

The FiiO S15 Streamer Network Player stands out with its sleek black chassis and robust construction. Weighing in at 17.46 pounds, it feels incredibly solid, almost like it’s built to last a lifetime. Its dimensions of 16 x 12 x 4 inches make it a perfect fit for most audio setups, blending seamlessly into any entertainment center. The 7.84-inch automotive-grade color display isn’t just large; it’s vibrant and crisp, making navigation a breeze. The dual knobs and virtual buttons, coupled with Bluetooth and app-based remote controls, give it a modern yet intuitive touch. While I appreciated the attention to detail, I found the standard chassis width of 430mm somewhat limiting for smaller spaces. Still, it’s a device that screams premium from every angle.

Performance and Audio Quality

I’ve tested quite a few audio streamers, but the AKM flagship DAC combination—AK4191+AK4499EX—in the S15 is genuinely impressive. The fully separated digital/analog architecture works wonders for reducing noise and elevating the signal-to-noise ratio. The difference in sound resolution and tonal clarity is noticeable, especially when streaming high-quality audio. Pairing it with my external DAC and amplifier, I was able to experience reference-grade sound performance that felt immersive and balanced. The addition of dual ACCUSILICON AS318-B femtosecond oscillators ensures incredibly precise decoding, and I couldn’t help but admire the accuracy in digital outputs. However, audiophiles might notice a slight lack of warmth in certain genres, which may be a personal preference rather than a flaw.

Positives

Choosing just a few key benefits of this streamer is no easy task, but here are my highlights:

• The Android 12 operating system allows smooth integration with major streaming apps like Roon Ready, AirPlay, and DLNA.
• Its versatile compatibility with NAS, local networks, and cloud servers ensures flexibility in accessing your music library.
• Multiple digital and analog interfaces, including HDMI/ARC, I2S output, and XLR balanced output, make it a perfect partner for any audio setup.
• The 7.84-inch screen is not just big but also highly responsive and easy to navigate.

Areas for Improvement

While the FiiO S15 delivers on many fronts, there are areas of concern that need mentioning:

• The price point might be steep for casual users who aren’t fully committed to high-fidelity audio.
• With such a comprehensive feature set, the learning curve for beginners could be intimidating.
• The size and weight make it less portable, which might not suit users with limited space.
• The customer review rating of 2.8 stars raises questions about long-term reliability or potential issues that may arise.

User Experience and Interface

Navigating through the custom horizontal screen interface of the S15 was straightforward. I especially liked how seamlessly it installs streaming apps without any noticeable lag. The Roon Ready and Bluetooth network streaming worked flawlessly, and I could feel the effort put into optimizing user experience. Whether I used the dual knobs for local operation or controlled it remotely via the app, it felt intuitive. However, I did experience a bit of delay when using the USB recording (DVR) feature, which could frustrate users expecting instantaneous responses.

Competing Products

When comparing the S15 to popular alternatives like the Bluesound NODE and Cambridge Audio CXN V2, a few differences stand out. The NODE, for example, offers a compact and portable design, making it more suitable for users with smaller setups. However, it lacks the extensive digital and analog interfaces of the S15. On the other hand, the CXN V2 matches the S15 in terms of audio quality, but its interface feels slightly dated. The S15’s 7.84-inch display and Android 12 integration give it an edge in usability, though the CXN V2 might appeal more to those who prefer a streamlined, minimalist design.

Cost Efficiency

I’d describe the S15 as a smart spending choice for audiophiles who prioritize sound quality and versatility. While it’s not the cheapest option out there, its feature-rich design, robust build, and extensive connectivity options justify the investment. Compared to similar products, the S15 offers an impressive price-to-quality ratio, especially for those using it as the centerpiece of a high-end audio system. However, if you’re just dipping your toes into the world of high-fidelity audio, there are more budget-friendly alternatives that might suit your needs better.
