Both are desktop amplifiers, $1099 against $699. This page puts them side by side on the only three things a maker can be held to — power, output impedance and noise — and then asks the question that actually matters: which headphones do they treat differently?
On raw power they are level: each reaches 100 dB on 567 of the 567 non-electrostatic models here.
| Specification | Gustard H26 | Singxer SA-1 |
|---|---|---|
| Power into 32Ω | 9.7 W | 5.5 W |
| Power into 150Ω | 2.1 W | 1.6 W |
| Power into 300Ω | 1.0 W | 785 mW |
| Power into 600Ω | 517 mW | 380 mW |
| Output impedance | 0.1 Ω | 1.4 Ω |
| Output noise | not published | 0.3 µV |
| Price | $1099 | $699 |
| Headphones it reaches 100 dB on out of 567 | 567 | 567 |
A figure marked not published is missing from the maker’s own material, which is not the same as being good or bad. Where one of these two publishes a number and the other does not, the comparison on that axis cannot be made at all — and saying so is more useful than guessing.
On power they are interchangeable across this whole database: there is no headphone here that one reaches 100 dB on and the other does not.
51 headphones are left alone by the Gustard H26 under the one-eighth rule but coloured by the Singxer SA-1 (64 Audio Aspire 1, 64 Audio Fourte, 64 Audio Nio, 48 more).
567 of the 567 models here reach 100 dB on both. That is a power count and nothing more; whether either source suits a given headphone also depends on the two lines above.
Each has a page of its own with every power figure traced to what the maker published and a full headphone list: Gustard H26 and Singxer SA-1. Or put either against your own headphones in the source comparison tool.
