Shanling SM90 Disrupts the Streaming DAC Landscape with HDMI ARC and a Focus on User Control
Shanling’s SM90 is a touchscreen-enabled streaming DAC aiming directly at the established Eversolo ecosystem. Priced under $1,000, it distinguishes itself with integrated HDMI ARC support, a feature largely absent in competitors, and a commitment to open standards. This isn’t merely another streamer. it’s a statement about user agency in a market increasingly dominated by walled gardens. The device, rolling out in limited quantities this week, represents a significant shift towards more versatile and adaptable audio solutions.
The current streaming DAC market is bifurcated. You have the closed ecosystems – reckon Bluesound or Sonos – offering seamless integration but limited customization. Then you have the more open, but often less polished, solutions built around Raspberry Pi and software like Volumio or Moode Audio. The SM90 attempts to bridge this gap, offering a premium, all-in-one experience with a surprising degree of flexibility. It’s a calculated move, especially given the recent antitrust scrutiny surrounding larger tech companies and their control over digital content distribution.
The M5 Architecture: A Deep Dive into Processing Power
At the heart of the SM90 lies a Rockchip RK3588 SoC, featuring a quad-core ARM Cortex-A76 processor and a Mali-G610 MP4 GPU. However, the real differentiator is the integrated Neural Processing Unit (NPU). While Shanling doesn’t disclose the NPU’s tera-operations per second (TOPS) rating, its presence suggests a future-proofing strategy. The NPU isn’t currently leveraged for audio processing – the RK3588’s CPU handles that – but it opens the door to potential AI-powered features like real-time upscaling or noise reduction. This represents a subtle but important distinction. Many competitors rely solely on CPU power for these tasks, leading to performance bottlenecks. The RK3588’s performance is comparable to Apple’s M1 in certain workloads, though thermal management is a key consideration. CNX Software’s comparison of RK3588-based boards highlights the SoC’s versatility.
The SM90 supports a wide range of audio codecs, including native DSD playback up to DSD512 and PCM up to 32bit/768kHz. It utilizes a dual ESS Sabre ES9038Q2M DAC chip configuration, operating in mono mode for improved channel separation. This is a common practice in high-end audio, but Shanling’s implementation is noteworthy for its low noise floor and dynamic range. The device also features a fully discrete Class A/B analog output stage, further enhancing audio fidelity.
HDMI ARC: A Game Changer for Simplified Setup
The inclusion of HDMI ARC (Audio Return Channel) is arguably the SM90’s most compelling feature. Most streaming DACs require a separate connection to your TV or projector for audio playback. HDMI ARC simplifies this process, allowing the SM90 to receive audio directly from your TV via a single HDMI cable. This is particularly useful for users who primarily consume content from streaming services on their TVs. It also eliminates the necessitate for a separate remote control, as the SM90 can be controlled using your TV’s remote. However, it’s crucial to note that HDMI ARC bandwidth limitations may restrict support for lossless audio formats like Dolby TrueHD or DTS-HD Master Audio. The SM90 supports eARC (enhanced ARC), which offers increased bandwidth, but compatibility will depend on your TV’s capabilities.
This move directly challenges the dominance of Eversolo, which, while offering excellent sound quality, lacks native HDMI ARC support. It’s a clear indication that Shanling is targeting users who prioritize convenience and ease of use.
The Open Ecosystem Advantage: API Access and Third-Party Integration
Shanling has taken a surprisingly open approach to software development, providing an API for third-party developers. This allows developers to create custom apps and integrations for the SM90, extending its functionality beyond what Shanling provides out of the box. This is a significant departure from the closed ecosystems of many competitors. The API documentation, while still in its early stages, covers basic functions like playback control, volume adjustment, and metadata access. The preliminary API documentation is available on GitHub, showcasing Shanling’s commitment to transparency.
“The decision to open up the API was deliberate. We desire to empower users to customize their experience and build a community around the SM90. We believe that open ecosystems are more innovative and resilient in the long run,” says Frank Chen, Shanling’s Head of Software Development.
This openness also has implications for cybersecurity. While an open API introduces potential security risks, it also allows for greater scrutiny and faster identification of vulnerabilities. Shanling has implemented end-to-end encryption for all network communications and regularly releases security updates. However, the long-term security of the platform will depend on the vigilance of both Shanling and the third-party developer community.
What This Means for Enterprise IT and the Future of Audio Streaming
The SM90’s versatility extends beyond the consumer market. Its open API and robust feature set make it a viable option for enterprise applications, such as digital signage or background music systems. The ability to remotely manage and control the device via the API is particularly appealing for businesses. The SM90’s support for a wide range of streaming services and audio formats ensures compatibility with existing infrastructure.
The rise of streaming DACs like the SM90 is also accelerating the fragmentation of the audio streaming market. Consumers are no longer limited to the streaming services and hardware platforms dictated by large tech companies. They have more choices than ever before, and they are increasingly demanding greater control over their audio experience. This trend is likely to continue, leading to a more competitive and innovative market.
The 30-Second Verdict
The Shanling SM90 isn’t just a streaming DAC; it’s a statement. It’s a declaration that users deserve a premium audio experience without sacrificing control or flexibility. The HDMI ARC support is a game-changer, and the open API is a testament to Shanling’s commitment to innovation. While the software is still evolving, the SM90 has the potential to disrupt the streaming DAC landscape and challenge the dominance of established players.
The price point, hovering around $899, positions it competitively against the Eversolo DMP-A6, but the SM90’s added features and open architecture give it a distinct advantage. It’s a compelling option for audiophiles, home theater enthusiasts, and anyone who values a versatile and customizable audio solution. Darko.Audio’s initial review provides a comprehensive overview of the device’s features and performance.
The SM90’s success will hinge on Shanling’s ability to maintain its commitment to open standards and provide ongoing software support. But if they can deliver on that promise, the SM90 has the potential to become a defining product in the streaming DAC market.
