Gustard DAC-X30
Gustard DAC-X30: A wired network/digital DAC feeding a compatible preamp or power-amp input with controlled level.
Evidence checked / updated: 2026-10-13. Manufacturer claims and editorial system-fit assessment. No SoundPath Lab listening or measurement test.
Verified documentation
- Inputs: USB/LAN/I²S to PCM32/768 and nativeDSD512;coaxial/AES/opticalPCM24/192 and DoP64
- Outputs: FIXED:RCA2.5Vrms,XLR5.1Vrms,both100Ω;variable attenuation0 to−90dB
- Clock / control: 50Ω10MHz BNC input;12V trigger in/out;streamer web control and upgrade at X30.local
- Bandwidth: 20Hz–20kHz ±0.2dB at VIVID setting;THD+N<0.0002% at1kHz,load not specified
- Critical conditions: I²S HDMI-shaped ports are not TV HDMI. Match pinout/DSD flag; both mains-voltage selectors must match
Best for
A wired network/digital DAC feeding a compatible preamp or power-amp input with controlled level.
Avoid if
Not a headphone/power amplifier or independently certified network-service compatibility.
Limits and unknowns
Fixed output bypasses attenuation; reduce downstream level before changing modes. Remote, streamer firmware, support duration and sonic clock claims are not independently tested.
Current verdict
A wired network/digital DAC feeding a compatible preamp or power-amp input with controlled level.
Why it fits
Use a compatible external DAC where the output is digital-only, an appropriate local network and supported control application. A protocol listing does not guarantee every subscription, region or DAC combination.
What it can replace
Can fill this role, subject to the stated conditions: A wired network/digital DAC feeding a compatible preamp or power-amp input with controlled level.
What it cannot replace
Not a headphone/power amplifier or independently certified network-service compatibility.
What SoundPath Lab tested
SoundPath Lab reviewed the listed exact-model primary documents and source discrepancies. No device was independently auditioned, measured, stress-tested or firmware-retested.
What remains untested
Actual sonic balance, distortion/output under load, room/ear fit, latency, long-term reliability and host-specific behaviour remain untested. Fixed output bypasses attenuation; reduce downstream level before changing modes. Remote, streamer firmware, support duration and sonic clock claims are not independently tested.
System conditions
Use a compatible external DAC where the output is digital-only, an appropriate local network and supported control application. A protocol listing does not guarantee every subscription, region or DAC combination.
Alternatives by need
Compare Matrix TS-1 when TV/headphone/analogue inputs matter, or a retained external DAC plus TT-1 when only network transport is missing.
Keep or upgrade
Keep a working system that already meets this use case. Upgrade only if the documented feature or connection solves the specific limitation: Fixed output bypasses attenuation; reduce downstream level before changing modes. Remote, streamer firmware, support duration and sonic clock claims are not independently tested.
When to reassess
Reassess on a verified hardware/document revision, material support or compatibility change, unresolved-source clarification, or accepted independent test. No arbitrary calendar delay or lifetime guarantee.
Ownership evidence
No new six-month ownership evidence was added; existing owner and issue records remain unchanged.
Firmware, manual and support
Use the documented connection and applicable official support workflow. This review does not establish the latest installed firmware, universal host compatibility or resolution of any owner issue. Current local stock, authorized sales, launch/shipping dates and transaction price are not established by this documentation review. Existing dated price evidence remains historical. Warranty territory, exclusions, battery/consumable terms, repair availability and long-term support must be checked with the applicable official policy; no universal support end date is inferred.

Revision record
2026-10-13 — Promoted from L0 to L2 after model-level evidence review. Stable product identity retained; source conflicts and untested behavior remain visible. L2 is evidence coverage, not independent test acceptance or automatic recommendation.
