Blessing 2 vs Blessing 2 Dusk: which needs more amplifier?

The Moondrop Blessing 2 is 22Ω at 100.4 dB/mW; the Moondrop Blessing 2 Dusk is 22Ω at 106.0 dB (no figure from the maker at all). 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 5.6 dB more than the Blessing 2 Dusk to reach the same loudness — 0.91 mW against 0.25 mW.

One caution before reading the rows. For Moondrop Blessing 2 Dusk the maker publishes no sensitivity figure at all. The number in the table was collected when this database was first built and has never been traced to a manufacturer document, so treat every row below it as an estimate rather than a specification.

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.

2 sources stay below the audible-hiss threshold with the Blessing 2 but cross it with the Blessing 2 Dusk (FiiO BTR11, Rupert Neve RNHP).

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 Blessing 2 Dusk. Each figure on this page is labelled on those pages with where it came from, including the ones Moondrop never published — what that maker publishes, counted.
