Blessing 2 vs DARKSABER: which needs more amplifier?

The Moondrop Blessing 2 is 22Ω at 100.4 dB/mW; the Moondrop DARKSABER is 22Ω at 111.4 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 Blessing 2 needs 11.0 dB more than the DARKSABER to reach the same loudness — 0.91 mW against 0.07 mW.

Where the two part company

Every source in the database that drives one of them drives the other. On power, the choice between these two changes nothing about what amplifier you need.

15 sources stay below the audible-hiss threshold with the Blessing 2 but cross it with the DARKSABER (FiiO BTR11, FiiO K11 R2R, Lake People G103-S Mk II, 12 more).

280 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: Moondrop Blessing 2 and Moondrop DARKSABER. Every figure on this page comes from what Moondrop published, or is derived from it — what that maker publishes, counted.
