Both are desktop amplifiers, $200 against $249. 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 | Schiit Magni Piety | Topping A30 Pro |
|---|---|---|
| Power into 32Ω | 1.0 W | 5.5 W |
| Power into 150Ω | 446 mW | 1.4 W |
| Power into 300Ω | 400 mW | 840 mW |
| Power into 600Ω | 200 mW | 420 mW |
| Output impedance | 0.6 Ω | 0.1 Ω |
| Output noise | not published | 0.3 µV |
| Price | $200 | $249 |
| 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.
1 headphone is left alone by the Topping A30 Pro under the one-eighth rule but coloured by the Schiit Magni Piety (Symphonium Titan).
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: Schiit Magni Piety and Topping A30 Pro. Or put either against your own headphones in the source comparison tool.
