The Dan Clark Audio Stealth is 23Ω at 90.0 dB/mW; the Sony MDR-MV1 is 24Ω at 100.0 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 Dan Clark Audio Stealth needs 10.0 dB more than the Sony MDR-MV1 to reach the same loudness — 10 mW against 1.0 mW.
| Specification | Dan Clark Audio Stealth | Sony MDR-MV1 |
|---|---|---|
| Impedance | 23 Ω | 24 Ω |
| Sensitivity | 90.0 dB/mW | 100.0 dB/mW |
| Sensitivity (voltage) | 106.4 dB/V | 116.2 dB/V |
| Power for 100 dB | 10 mW | 1.0 mW |
| Voltage for 100 dB | 0.48 V | 0.15 V |
| Current for 100 dB | 20.9 mA | 6.5 mA |
| Highest source impedance that leaves them alone (one-eighth rule) | 2.88 Ω | 3.00 Ω |
| Sources that reach 100 dB out of 280 | 279 | 280 |
1 of the 280 sources has the power for the Sony MDR-MV1 but not for the Dan Clark Audio Stealth — Steinberg UR22C.
279 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: Dan Clark Audio Stealth and Sony MDR-MV1. Every figure on this page comes from what Dan Clark Audio and Sony published, or is derived from it — what Dan Clark Audio publishes and what Sony publishes, both counted.
