Both are desktop DAC/amps, $1499 against $1600. 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 | Matrix mini-i Pro 4 | Violectric V226 |
|---|---|---|
| Power into 32Ω | 1.2 W | 2.2 W |
| Power into 150Ω | 366 mW | 2.6 W |
| Power into 300Ω | 260 mW | 1.8 W |
| Power into 600Ω | 130 mW | 900 mW |
| Output impedance | 11 Ω | 0.25 Ω |
| Output noise | not published | 6.15 µV |
| Price | $1499 | $1600 |
| 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.
520 headphones are left alone by the Violectric V226 under the one-eighth rule but coloured by the Matrix mini-i Pro 4 (64 Audio Aspire 1, 64 Audio Fourte, 64 Audio Nio, 517 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: Matrix mini-i Pro 4 and Violectric V226. Or put either against your own headphones in the source comparison tool.
