Both are desktop amplifiers, $600 against $600. 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?
The iFi iCAN Pro reaches 100 dB on 567 of the 567 models here, the Soncoz SGA1 on 566.
| Specification | iFi iCAN Pro | Soncoz SGA1 |
|---|---|---|
| Power into 32Ω | 4.0 W | 407 mW |
| Power into 150Ω | 1.2 W | 207 mW |
| Power into 300Ω | 600 mW | 210 mW |
| Power into 600Ω | 300 mW | 105 mW |
| Output impedance | 0.5 Ω unverified | 0.1 Ω |
| Output noise | 25 µV unverified | 1.8 µV |
| Price | $600 | $600 |
| Headphones it reaches 100 dB on out of 567 | 567 | 566 |
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.
1 headphone reaches 100 dB on the iFi iCAN Pro but not on the Soncoz SGA1 — Symphonium Titan.
566 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 a full headphone list and the provenance of every figure — worth opening here, because iFi iCAN Pro has published no electrical specification at all and everything above comes from independent measurement: iFi iCAN Pro and Soncoz SGA1. Or put either against your own headphones in the source comparison tool.
