Both are desktop amplifiers, $629 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 Lake People G111 Mk II reaches 100 dB on 567 of the 567 models here, the Soncoz SGA1 on 566.

| Power into 600Ω | 600 mW | 105 mW |
| Output impedance | 0.125 Ω | 0.1 Ω |
| Output noise | 6.9 µV | 1.8 µV |

| 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 Lake People G111 Mk II but not on the Soncoz SGA1 — Symphonium Titan.
114 headphones stay below the audible-hiss threshold on the Soncoz SGA1 but cross it on the Lake People G111 Mk II (64 Audio Aspire 1, 64 Audio Fourte, 64 Audio Nio, 111 more).
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 every power figure traced to what the maker published and a full headphone list: Lake People G111 Mk II and Soncoz SGA1. Or put either against your own headphones in the source comparison tool.
