The Moondrop Blessing 2 Dusk is 22Ω at 106.0 dB (no figure from the maker at all); the Moondrop ILLUSTRIOUS is 25Ω at 108.0 dB/mW. This page covers what they ask of an amplifier, not how they sound.
The Blessing 2 Dusk needs 2.0 dB more than the ILLUSTRIOUS to reach the same loudness — 0.25 mW against 0.16 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.
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.
4 sources stay below the audible-hiss threshold with the Blessing 2 Dusk but cross it with the ILLUSTRIOUS (FiiO K11 R2R, Schiit Valhalla 3, Lake People G111 Mk II, 1 more).
280 of the 280 sources here reach 100 dB on both.
The Blessing 2 Dusk is more demanding than 23% of the 567 non-electrostatic models in this database; the ILLUSTRIOUS than 18%.

| Source | Price | Headroom, Blessing 2 Dusk | Headroom, ILLUSTRIOUS | Output impedance | Noise |
|---|---|---|---|---|---|
| JadeAudio JA11 | $20 | 19.1 dB | 21.7 dB | 0.5 Ω | 1.7 µV |
| FiiO KA11 | $29 | 29.4 dB | 31.2 dB | 0.7 Ω | 1.7 µV |
| FiiO BTR13 | $59 | 26.3 dB | 28.2 dB | 0.6 Ω | 1.0 µV |
Of the 280 sources here, 280 reach 100 dB on both. 65 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 cheapest of the 65 is the JadeAudio JA11, at $20. It leaves 19.1 dB of headroom on the Blessing 2 Dusk and 21.7 dB on the ILLUSTRIOUS, its output impedance is 0.5 Ω against a one-eighth limit of 2.75 Ω and 3.12 Ω, and its noise figure puts the hiss floor 13 dB and 11 dB below the 20 dB SPL this site treats as the point where a quiet room stops hiding it.
Both have a page of their own. In full: Moondrop Blessing 2 Dusk and Moondrop ILLUSTRIOUS. 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.
