Unboxing and First Impressions
The Gustard X26 Mark III arrived in sleek, understated packaging. The unit itself is compact and well-built, exuding a premium feel. The OLED touchscreen display is bright and easy to read, and the overall design is both elegant and functional.
Initial setup was straightforward. Connecting to my existing network and streaming sources was seamless. The intuitive interface made navigating the various settings and menus a breeze.
Streaming Capabilities and App Integration
Unlike many modern streamers that rely on proprietary apps, the Gustard X26 Mark III embraces third-party compatibility. It works flawlessly with popular protocols like Roon, UPnP, and AirPlay, providing flexibility in how you manage your music library.
This approach eliminates the need to download yet another app, a refreshing change in a market saturated with proprietary software. While it might limit support for some streaming services, the workaround with established protocols is efficient.
DAC Performance and Technology
At its core, the X26 Mark III is a high-performance DAC employing two ESS9039 Pro DAC chips. This dual-chip configuration, alongside the 8-channel architecture, results in impressively low distortion and exceptional clarity.
The Gustard also boasts a high-performance clock and allows for external clocking, further enhancing sonic accuracy. The use of class A discrete circuitry in the output stage rounds out a truly impressive specification sheet.
Preamp Functionality and Ease of Use
The X26 Mark III integrates a preamp function, enabling direct connection to power amplifiers. The volume control, ranging from 90dB to 0dB, is smoothly implemented and easy to adjust.
Switching between preamp and fixed output modes is exceptionally intuitive. Simply turning the volume all the way up and then one click further activates the fixed output; decreasing the volume reverts to preamp mode. This simple design is a refreshing change from complicated menu navigation.
Connectivity and Digital Inputs
A wide array of digital inputs caters to various sources including TVs, dedicated streamers, and CD transports. The unit supports high sampling rates, up to DSD and PCM 64, with MQA compatibility across all inputs.
For those who prefer higher sampling rates (DSD512), USB and I2S connections offer superior performance. Different I2S configurations are supported, granting maximum flexibility when pairing with different devices.
Sound Quality and Listening Experience
The Gustard X26 Mark III delivers a neutral sound signature with a touch of warmth and smoothness. While detailed and revealing, it avoids being overly clinical or analytical, which can sometimes be associated with Saber DACs.
The soundstage is impressively wide and deep. The unit's pitch-black background allows for the appreciation of subtle details without sacrificing power or impact, even at high volumes.
Comparisons and Conclusion
Compared to other DACs in its price range (around $1600), the X26 Mark III holds its own. While some competitors offer warmer or more tube-like sounds, the Gustard stands out with its exceptional neutrality, detail retrieval, and forgiving nature at high volumes.
The Gustard X26 Mark III is a compelling choice for audiophiles seeking a versatile, high-performing DAC with exceptional sound quality. Its ease of use, intuitive design, and excellent implementation make it a worthwhile investment. While some may prefer the warmer sound signature of competitors like the Live Harmony, the X26 Mark III provides a more neutral and detailed listening experience.
