Freya Vanir vs Loki Divine Mark: which needs more amplifier?

The Kinera Freya Vanir is 16Ω at 88.0 dB/mW; the Kinera Loki Divine Mark is 14Ω at 105.0 dB (no reference unit printed). This page is only about what they ask of an amplifier — not how they sound, which no specification on either sheet can tell you.

The Freya Vanir needs 17.0 dB more than the Loki Divine Mark to reach the same loudness — 16 mW against 0.32 mW.

One caution before reading the rows. Kinera Loki Divine Mark printed a decibel figure with no reference unit, so this page reads it as per milliwatt. If it is really per volt, that model needs far more than the table says. Why the two readings differ by so much.

Where the two part company

18 of the 280 sources have the power for the Loki Divine Mark but not for the Freya Vanir — Apple USB-C dongle (US), Apple USB-C dongle (EU), JadeAudio JA11, 15 more.

4 sources are low enough in output impedance for the Freya Vanir under the one-eighth rule but not for the Loki Divine Mark (Schiit Vali 2+, Astell&Kern HC3, RME Fireface UFX II, 1 more).

5 sources stay below the audible-hiss threshold with the Freya Vanir but cross it with the Loki Divine Mark (FiiO BTR11, FiiO K11 R2R, Lake People G111 Mk II, 2 more).

262 of the 280 sources here reach 100 dB on both. That count is about power only — the output-impedance and hiss lines above are separate questions, and a source can pass this one and fail those.

What each one needs from 80 to 105 dB

The gap between these two in decibels does not change with volume — it is a property of the two headphones. What changes is the size of the numbers, and it changes fast: every 10 dB costs ten times the power. The row that matters is the one nearest the level you listen at, and for most people that is nearer the top of this table than the bottom.

The Freya Vanir is more demanding than 87% of the 567 non-electrostatic models in this database; the Loki Divine Mark than 20%. Both figures use the same measure as the rest of the site: whichever runs out first against a 2 V, 100 mW dongle, voltage or power.

105 dB is included because forum power figures are usually quoted there or higher. It is also a level that damages hearing in minutes — how many minutes is its own calculator.

The cheapest source that satisfies both

FiiO BTR13$598.8 dB25.2 dB0.6 Ω1.0 µV
iBasso DC03 Pro$694.9 dB21.3 dB0.12 Ω0.9 µV

Of the 280 sources here, 262 reach 100 dB on both. That is the easy axis. 64 of them also publish an output impedance low enough for both under the one-eighth rule and a noise figure that stays below the audible-hiss threshold with both — the rest either fail one of those or never printed the number at all, and 191 of them are in the second group.

The cheapest of the 64 is the FiiO KA11, at $29. It leaves 11.9 dB of headroom on the Freya Vanir and 28.3 dB on the Loki Divine Mark, its output impedance is 0.7 Ω against a one-eighth limit of 2.00 Ω and 1.75 Ω, and its noise figure puts the hiss floor 29 dB and 12 dB below the 20 dB SPL this site treats as the point where a quiet room stops hiding it.

Cheapest that satisfies three published numbers is not the same as best, and none of it is about how either headphone sounds. To put either model against a source this page does not mention, or to change the target loudness, use the amplifier matcher.

What each sheet prints, and what it is worth

ModelAs printedToleranceStandard
Freya Vanir20Hz – 20kHznot printednot printed
Loki Divine Mark20Hz - 50kHz ultra-widebandnot printednot printed

Kinera prints 20Hz – 20kHz for the Freya Vanir and 20Hz - 50kHz ultra-wideband for the Loki Divine Mark.

Loki Divine Mark: Kinera prints “ultra-wideband” inside the specification cell, next to the numbers and in place of the tolerance that would have said what the range means.

Neither range has a tolerance printed beside it, and that is the whole of what this section can tell you. A wider range on one sheet is not deeper bass or more treble on that headphone: without a tolerance, neither number says how loud either model is at the ends of its own range, so the difference between the two is a difference between two pieces of marketing copy. A ±dB figure is what turns a range into a specification, and of the 490 models whose maker prints a range, 58 print it.

None of this is a measurement. What each maker publishes, and what it is worth, is set out in the frequency response audit.

Both pages in full

Each model has a page of its own with the full source list, the hiss estimate and the provenance of every figure above: Kinera Freya Vanir and Kinera Loki Divine Mark. Each figure on this page is labelled on those pages with where it came from, including the ones Kinera never published — what that maker publishes, counted.
