Schiit Valhalla 2 vs Schiit Vali 3

Both are desktop amplifiers, $349 against $149. 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 Schiit Vali 3 reaches 100 dB on 567 of the 567 models here, the Schiit Valhalla 2 on 561.

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.

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 Valhalla 2 publishes at 300 Ω and at 600 Ω; Schiit Vali 3 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 32 Ω only the Schiit Vali 3 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.

6 headphones reach 100 dB on the Schiit Vali 3 but not on the Schiit Valhalla 2 — Moondrop COSMO, Moondrop PARA, Symphonium Crimson, 3 more.

521 headphones are left alone by the Schiit Vali 3 under the one-eighth rule but coloured by the Schiit Valhalla 2 (64 Audio Aspire 1, 64 Audio Fourte, 64 Audio Nio, 518 more).

561 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.

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 Campfire Audio Andromeda 2020: Schiit Vali 3 has +20 dB of headroom there against +9 dB. 11 dB is about 13 times the power, which matters for peaks rather than for how loud the music sits.

The hiss columns are empty for Schiit Valhalla 2 because that maker publishes no output noise figure. That is a gap in the specification, not a quiet amplifier, and it is left blank here rather than filled with a plausible number.

The Schiit Valhalla 2 costs $200 more than the Schiit Vali 3, and on these three axes the money buys nothing: among the 567 models here there is not one that the Schiit Valhalla 2 handles and the Schiit Vali 3 does not — not on power, not on the one-eighth rule, not on hiss. The traffic runs the other way: the cheaper Schiit Vali 3 drives 6 models to 100 dB and leaves 521 alone under the one-eighth rule that the Schiit Valhalla 2 does not.

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 Valhalla 2 and Schiit Vali 3. Or put either against your own headphones in the source comparison tool.
