Both are portable amplifiers, $2595 against $650. 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 Chord Hugo 2 reaches 100 dB on 567 of the 567 models here, the Chord Mojo 2 on 566.
| Specification | Chord Hugo 2 | Chord Mojo 2 |

| Power into 150Ω | 171 mW | 145 mW |
| Power into 300Ω | 94 mW | 90 mW |
| Power into 600Ω | 47 mW | 45 mW |
| Output impedance | 0.025 Ω | 0.06 Ω |
| Output noise | 2.6 µV | 2.7 µV |
| Price | $2595 | $650 |
| 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 Chord Hugo 2 but not on the Chord Mojo 2 — Symphonium Titan.
2 headphones stay below the audible-hiss threshold on the Chord Hugo 2 but cross it on the Chord Mojo 2 (KZ AS16 Pro, Shure SE315).
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: Chord Hugo 2 and Chord Mojo 2. Or put either against your own headphones in the source comparison tool.
