The Symphonium Crimson is 6.05Ω at 83.8 dB/mW; the Symphonium Triton is 8.3Ω at 86.2 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 Crimson needs 2.4 dB more than the Triton to reach the same loudness — 42 mW against 24 mW.
| Specification | Crimson | Triton |
|---|---|---|
| Impedance | 6.05 Ω | 8.3 Ω |
| Sensitivity | 83.8 dB/mW | 86.2 dB/mW |
| Sensitivity (voltage) | 106.0 dB/V | 107.0 dB/V |
| Power for 100 dB | 42 mW | 24 mW |
| Voltage for 100 dB | 0.50 V | 0.45 V |
| Current for 100 dB | 83.0 mA | 53.8 mA |
| Highest source impedance that leaves them alone (one-eighth rule) | 0.76 Ω | 1.04 Ω |
| Sources that reach 100 dB out of 280 | 166 | 229 |
63 of the 280 sources have the power for the Triton but not for the Crimson — FiiO SnowSky Tiny B, Tanchjim Stargate II, ddHiFi TC35Air, 60 more.
37 sources are low enough in output impedance for the Triton under the one-eighth rule but not for the Crimson (FiiO SnowSky Tiny B, FiiO KA15, FiiO BTR15, 34 more).
166 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: Symphonium Crimson and Symphonium Triton. Every figure on this page comes from what Symphonium published, or is derived from it — what that maker publishes, counted.
