Gustard AMP-H26 — Decision Profile
L2 Decision Profile · documentation + editorial assessment
Quick verdict
An analogue multi-input headphone/preamp hub behind a suitable DAC
Avoid if: A digital DAC or a common-ground balanced adapter
Evidence checked: 2026-10-17. Manufacturer documentation; no independent SoundPath Lab listening, measurement, compatibility or firmware retest.
System conditions
Unplug before verifying both mains selectors; lower gain/volume before listening, and never short balanced returns
Documented specifications
| Item | Specification and conditions |
|---|---|
| Analogue inputs | One RCA input, 4 kohms, 2–3 Vrms range; two XLR inputs, 8 kohms, 4–6 Vrms recommended, 12 Vrms max |
| Outputs | 6.35 mm single-ended, balanced 4.4 mm/4-pin XLR; RCA/XLR preouts at 100 ohms |
| Output condition | Headphone output impedance 0.05 ohms single-ended /0.1 ohms balanced; manual power ratings use different distortion limits |
Limits and source qualifications
Headphone load power/noise and fixed/variable routing untested; 9.7 W and 12 W figures have different distortion conditions
- The official PDF metadata contains H20 but the cover and operating body identify H26; this qualification is retained
Alternatives by need
AH90 includes conversion/network input, while H26 serves existing line sources and additional analogue input switching
Keep or upgrade
Keep a working system that already meets these requirements. Consider a change only when the documented connection, control or system role solves a specific unmet need; no measured sound-quality upgrade is claimed.
Evidence, support and reassessment
Review scope
Exact-model primary specification and connection sections cited below were reviewed. Source claims and editorial system-fit reasoning are distinct from independent listening, measurement, compatibility or firmware tests; none were added.
Actual sound, under-load output, room/ear fit, latency and long-term reliability remain untested. Existing scores, Builder qualification and owner/test records were not reassessed.
Firmware and regional support
Local stock, authorized sales, transaction prices and long-term support duration are not established by this documentation review. Dated regional announcements apply only to their stated territory and terms. Existing dated price and owner evidence is retained.
No installed firmware version or issue resolution was retested. Follow the exact-model official support workflow.
Reassess when evidence changes
Reassess on verified hardware or firmware changes, clarification of a source conflict, material support/compatibility changes, or accepted independent testing.
No new six-month ownership evidence was added; existing owner and issue records remain unchanged.
