Loki Divine Mark vs Mimisbrunnr: which needs more amplifier?

The Kinera Loki Divine Mark is 14Ω at 105.0 dB (no reference unit printed); the Kinera Mimisbrunnr is 43Ω at 88.3 dB/mW. 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 Mimisbrunnr needs 16.7 dB more than the Loki Divine Mark to reach the same loudness — 15 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

3 of the 280 sources have the power for the Loki Divine Mark but not for the Mimisbrunnr — Apple USB-C dongle (EU), Steinberg UR22C, Sony NW-A306.

5 sources are low enough in output impedance for the Mimisbrunnr under the one-eighth rule but not for the Loki Divine Mark (Schiit Vali 2+, Astell&Kern HC3, Shanling H5, 2 more).

4 sources stay below the audible-hiss threshold with the Mimisbrunnr but cross it with the Loki Divine Mark (FiiO BTR11, FiiO K11 R2R, Lake People G111 Mk II, 1 more).

277 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.

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 Loki Divine Mark and Kinera Mimisbrunnr. 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.
