Gustard H26 vs Schiit Mjolnir 3

Short answer

  • More power: the Gustard H26, with 9.70 W into 32 Ω; the Schiit Mjolnir 3 has 1.00 W. The Gustard H26 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 Gustard H26 publishes no noise figure.
  • Price: the Gustard H26 costs $100 less, and wherever both makers publish a figure the Schiit Mjolnir 3 shows no advantage for the extra money.

Both are desktop amplifiers, $1099 against $1199.

The Gustard H26 reaches 100 dB on 567 of the 567 models here, the Schiit Mjolnir 3 on 566.

Not published means the maker leaves it out, so that axis cannot be compared.

Only the Schiit Mjolnir 3 has a separate balanced rating from its maker; through it, it reaches 100 dB on 567 of the 567 models here. The Gustard H26 may still have a balanced socket — its spec sheet simply gives no figure for one, so there is nothing to put beside it.

Both makers publish a power rating. Gustard H26 publishes at 32 Ω; Schiit Mjolnir 3 at 32 Ω and at 300 Ω. The other rows are worked out from those.

So the two columns are not equally firm row by row: at 300 Ω only the Schiit Mjolnir 3 figure is the maker’s own. On those rows the derived number is the one to doubt first.

What separates them

The headphones that tell them apart

1 headphone reaches 100 dB on the Gustard H26 but not on the Schiit Mjolnir 3 — Symphonium Titan.

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

On real headphones

Headroom and hiss on 8 models, both sources

Headroom is at a 100 dB SPL peak.

The widest gap on the list is the HiFiMAN HE400se: Gustard H26 has +30 dB of headroom there against +20 dB. 10 dB is about 9.7 times the power, which matters for peaks rather than for how loud the music sits.

The hiss columns are empty for Gustard H26 because that maker publishes no output noise figure.

What the price difference buys

The gap in dollars, against the gap in numbers

The Schiit Mjolnir 3 costs $100 more than the Gustard H26, 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 Gustard H26 does not — not on power, not on the one-eighth rule, not on hiss. The traffic runs the other way: the cheaper Gustard H26 drives one model to 100 dB that the Schiit Mjolnir 3 does not.

Only published figures count here; blank axes are counted separately.
