Schiit Mjolnir 3 vs SMSL VMV P2 MK2

Short answer

  • More power: the SMSL VMV P2 MK2, with 2.00 W into 32 Ω; the Schiit Mjolnir 3 has 1.00 W (balanced: 8.00 W against 2.00 W). The SMSL VMV P2 MK2 drives 1 headphone to 100 dB that the Schiit Mjolnir 3 cannot (Symphonium Titan).
  • Hiss with sensitive IEMs: cannot be compared — the maker of the SMSL VMV P2 MK2 publishes no noise figure.
  • Price: the SMSL VMV P2 MK2 costs $39 less, and wherever both makers publish a figure the Schiit Mjolnir 3 shows no advantage for the extra money.

Both are desktop amplifiers, $1199 against $1160.

The SMSL VMV P2 MK2 reaches 100 dB on 567 of the 567 models here, the Schiit Mjolnir 3 on 566.

Both makers publish a power rating. Schiit Mjolnir 3 publishes at 32 Ω and at 300 Ω; SMSL VMV P2 MK2 at 32 Ω, at 300 Ω and at 600 Ω. The other rows are worked out from those.

So the two columns are not equally firm row by row: at 600 Ω only the SMSL VMV P2 MK2 figure is the maker’s own. On those rows the derived number is the one to doubt first.

What the labels mean.

The headphones that tell them apart

1 headphone reaches 100 dB on the SMSL VMV P2 MK2 but not on the Schiit Mjolnir 3 — Symphonium Titan.

566 of the 567 models here reach 100 dB on both.

Headroom and hiss on 8 models, both sources

Headroom is at a 100 dB SPL peak.

The widest gap on the list is the Campfire Audio Andromeda 2020: SMSL VMV P2 MK2 has +28 dB of headroom there against +18 dB. 9 dB is about 8 times the power, which matters for peaks rather than for how loud the music sits.

The hiss columns are empty for SMSL VMV P2 MK2 because that maker publishes no output noise figure.

The gap in dollars, against the gap in numbers

The Schiit Mjolnir 3 costs $39 more than the SMSL VMV P2 MK2, and on these three axes the money buys nothing: among the 567 models here there is not one that the Schiit Mjolnir 3 handles and the SMSL VMV P2 MK2 does not — not on power, not on the one-eighth rule, not on hiss. The traffic runs the other way: the cheaper SMSL VMV P2 MK2 drives one model to 100 dB that the Schiit Mjolnir 3 does not.
