Schiit Mjolnir 3 vs Violectric V222

Both are desktop amplifiers, $1199 against $1245. 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 Violectric V222 reaches 100 dB on 567 of the 567 models here, the Schiit Mjolnir 3 on 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.

Where each power figure comes from

Both makers publish a power rating, which is less common than the table above makes it look: of the 280 sources here, 209 publish a figure at at least one load and only 2 publish one at all four. Schiit Mjolnir 3 publishes at 32 Ω and at 300 Ω; Violectric V222 at 32 Ω, at 300 Ω and at 600 Ω. Every other row is worked out from those — between two published loads, or beyond them holding voltage constant, which understates rather than flatters.

So the two columns are not equally firm row by row: at 600 Ω only the Violectric V222 figure is the maker’s own. On those rows the derived number is the one to doubt first.

What each of these labels means, and why a derived figure is still worth printing, is set out in how this data was built.

The headphones that tell them apart

1 headphone reaches 100 dB on the Violectric V222 but not on the Schiit Mjolnir 3 — Symphonium Titan.

287 headphones stay below the audible-hiss threshold on the Violectric V222 but cross it on the Schiit Mjolnir 3 (64 Audio Aspire 1, 64 Audio Ocean, 64 Audio Solo, 284 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.

Headroom and hiss on 8 models, both sources

The counts above say how many models the two treat differently. This says by how much. The same 8 headphones appear on every page of this kind, ordered from the easiest to drive to the hardest, so a row can be read across pages as well as across columns. Headroom is at a 100 dB SPL peak.

The widest gap on the list is the Audeze LCD-2 Classic: Violectric V222 has +36 dB of headroom there against +29 dB. 7 dB is about 5.5 times the power, which matters for peaks rather than for how loud the music sits.

Hiss is this source’s own noise, in decibels SPL, in that headphone — not a rating. Below about 20 dB SPL it is under the threshold of hearing in a quiet room; a negative figure means it is far below it.

The gap in dollars, against the gap in numbers

The Violectric V222 costs $46 more than the Schiit Mjolnir 3. Out of the 567 models here, that difference buys 1 more model driven to 100 dB and 287 more models kept below the audible-hiss threshold.

Nothing runs the other way: there is no axis here on which the cheaper of the two does better.

Everything in this paragraph counts only figures the two makers published. An advantage on an axis one of them leaves blank cannot be counted, and is not counted — how often that happens is its own page.

Each has a page of its own with every power figure traced to what the maker published and a full headphone list: Schiit Mjolnir 3 and Violectric V222. Or put either against your own headphones in the source comparison tool.
