The Elysian Acoustic Labs Annihilator is 22Ω at 99.4 dB/mW; the Elysian Acoustic Labs Pilgrim is 9Ω at 100.5 dB/mW. This page covers what they ask of an amplifier, not how they sound.
The Annihilator needs 1.1 dB more than the Pilgrim to reach the same loudness — 1.1 mW against 0.89 mW.

| Sensitivity | 99.4 dB/mW | 100.5 dB/mW |
| Sensitivity (voltage) | 116.0 dB/V | 121.0 dB/V |
| Power for 100 dB | 1.1 mW | 0.89 mW |
| Voltage for 100 dB | 0.16 V | 90 mV |
| Current for 100 dB | 7.2 mA | 10.0 mA |
| Highest source impedance that leaves them alone (one-eighth rule) | 2.75 Ω | 1.12 Ω |
| Sources that reach 100 dB out of 280 | 280 | 280 |
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.
11 sources are low enough in output impedance for the Annihilator under the one-eighth rule but not for the Pilgrim (FiiO KA13, FiiO K11, Schiit Vali 2+, 8 more).
280 of the 280 sources here reach 100 dB on both.
The Annihilator is more demanding than 49% of the 567 non-electrostatic models in this database; the Pilgrim than 29%.
| dB SPL | Annihilator power | Annihilator voltage | Pilgrim power | Pilgrim voltage |
|---|---|---|---|---|
| 80 | 0.01 mW | 16 mV | 8.9 µW | 9 mV |
| 85 | 0.04 mW | 28 mV | 0.03 mW | 16 mV |
| 90 | 0.11 mW | 50 mV | 0.09 mW | 28 mV |
| 95 | 0.36 mW | 89 mV | 0.28 mW | 50 mV |
| 100 | 1.1 mW | 0.16 V | 0.89 mW | 90 mV |

| Source | Price | Headroom, Annihilator | Headroom, Pilgrim | Output impedance | Noise |
|---|---|---|---|---|---|
| JadeAudio JA11 | $20 | 12.5 dB | 9.8 dB | 0.5 Ω | 1.7 µV |
| FiiO KA11 | $29 | 22.8 dB | 21.9 dB | 0.7 Ω | 1.7 µV |
| FiiO BTR11 | $36 | 15.0 dB | 14.5 dB | 0.5 Ω | 8.0 µV |
Of the 280 sources here, 280 reach 100 dB on both. 62 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 62 is the JadeAudio JA11, at $20. It leaves 12.5 dB of headroom on the Annihilator and 9.8 dB on the Pilgrim, its output impedance is 0.5 Ω against a one-eighth limit of 2.75 Ω and 1.12 Ω, and its noise figure puts the hiss floor 19 dB and 14 dB below the 20 dB SPL this site treats as the point where a quiet room stops hiding it.
| Model | As printed | Tolerance | Standard |
|---|---|---|---|
| Annihilator | 20hz - 45khz | not printed | not printed |
| Pilgrim | 10hz~20khz | not printed | not printed |
Elysian Acoustic Labs prints 20hz - 45khz for the Annihilator and 10hz~20khz for the Pilgrim.
Neither range has a tolerance printed beside it, so a wider range on one sheet is not deeper bass or more treble.
Not a measurement; maker by maker.
Both have a page of their own. In full: Elysian Acoustic Labs Annihilator and Elysian Acoustic Labs Pilgrim. Every figure on this page comes from what Elysian Acoustic Labs published, or is derived from it — what that maker publishes, counted.
