The Elysian Acoustic Labs Apostle 2026 is 10Ω at 97.0 dB/mW; the Elysian Acoustic Labs Pilgrim Noir is 8.3Ω at 102.2 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 Apostle 2026 needs 5.2 dB more than the Pilgrim Noir to reach the same loudness — 2.0 mW against 0.60 mW.
| Specification | Apostle 2026 | Pilgrim Noir |
|---|---|---|
| Impedance | 10 Ω | 8.3 Ω |
| Sensitivity | 97.0 dB/mW | 102.2 dB/mW |
| Sensitivity (voltage) | 117.0 dB/V | 123.0 dB/V |
| Power for 100 dB | 2.0 mW | 0.60 mW |
| Voltage for 100 dB | 0.14 V | 71 mV |
| Current for 100 dB | 14.1 mA | 8.5 mA |
| Highest source impedance that leaves them alone (one-eighth rule) | 1.25 Ω | 1.04 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.
4 sources are low enough in output impedance for the Apostle 2026 under the one-eighth rule but not for the Pilgrim Noir (FiiO K11, FiiO BTR7, FiiO Q7, 1 more).
3 sources stay below the audible-hiss threshold with the Apostle 2026 but cross it with the Pilgrim Noir (FiiO BTR11, FiiO K11 R2R, 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: Elysian Acoustic Labs Apostle 2026 and Elysian Acoustic Labs Pilgrim Noir. Every figure on this page comes from what Elysian Acoustic Labs published, or is derived from it — what that maker publishes, counted.
