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.
| Specification | Blessing 2 | Blessing 2 Dusk |
|---|---|---|
| Impedance | 22 Ω | 22 Ω |
| Sensitivity | 100.4 dB/mW | 106.0 dB |
| Sensitivity (voltage) | 117.0 dB/V | 122.6 dB/V |
| Power for 100 dB | 0.91 mW | 0.25 mW |
| Voltage for 100 dB | 0.14 V | 74 mV |
| Current for 100 dB | 6.4 mA | 3.4 mA |
| Highest source impedance that leaves them alone (one-eighth rule) | 2.75 Ω | 2.75 Ω |
| Sources that reach 100 dB out of 280 | 280 | 280 |
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.
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.
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.
