The Symphonium Meteor is 9.7Ω at 90.9 dB/mW; the Symphonium Triton is 8.3Ω at 86.2 dB/mW. This page covers what they ask of an amplifier, not how they sound.
The Triton needs 4.7 dB more than the Meteor to reach the same loudness — 24 mW against 8.1 mW.
| Specification | Meteor | Triton |
|---|---|---|
| Impedance | 9.7 Ω | 8.3 Ω |
| Sensitivity | 90.9 dB/mW | 86.2 dB/mW |
| Sensitivity (voltage) | 111.0 dB/V | 107.0 dB/V |
| Power for 100 dB | 8.1 mW | 24 mW |
| Voltage for 100 dB | 0.28 V | 0.45 V |
| Current for 100 dB | 28.9 mA | 53.8 mA |
| Highest source impedance that leaves them alone (one-eighth rule) | 1.21 Ω | 1.04 Ω |
| Sources that reach 100 dB out of 280 | 271 | 229 |
42 of the 280 sources have the power for the Meteor but not for the Triton — Apple USB-C dongle (US), Generic CX31993 dongles, JadeAudio JA11, 39 more.
4 sources are low enough in output impedance for the Meteor under the one-eighth rule but not for the Triton (FiiO K11, FiiO BTR7, FiiO Q7, 1 more).
229 of the 280 sources here reach 100 dB on both.
The Triton is more demanding than 86% of the 567 non-electrostatic models in this database; the Meteor than 71%.
| dB SPL | Meteor power | Meteor voltage | Triton power | Triton voltage |

| Source | Price | Headroom, Meteor | Headroom, Triton | Output impedance | Noise |
|---|---|---|---|---|---|
| FiiO KA11 | $29 | 12.6 dB | 7.2 dB | 0.7 Ω | 1.7 µV |
| FiiO BTR13 | $59 | 9.5 dB | 4.1 dB | 0.6 Ω | 1.0 µV |
| iBasso DC03 Pro | $69 | 5.6 dB | 0.3 dB | 0.12 Ω | 0.9 µV |
Of the 280 sources here, 229 reach 100 dB on both. 61 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 61 is the FiiO KA11, at $29. It leaves 12.6 dB of headroom on the Meteor and 7.2 dB on the Triton, its output impedance is 0.7 Ω against a one-eighth limit of 1.21 Ω and 1.04 Ω, and its noise figure puts the hiss floor 24 dB and 28 dB below the 20 dB SPL this site treats as the point where a quiet room stops hiding it.
| Model | As printed | Tolerance | Standard |
|---|---|---|---|
| Meteor | 12Hz - 21kHz, ± 3 dB | ±3 dB | not printed |
| Triton | 11Hz - 21kHz, ± 3 dB | ±3 dB | not printed |
Symphonium prints 12Hz - 21kHz, ± 3 dB for the Meteor and 11Hz - 21kHz, ± 3 dB for the Triton.
Both sheets print a tolerance, which is rare enough to be worth pointing at: only 58 of the 490 models with a printed range do. These two ranges can be set against each other, because each of them says how far down the response is allowed to be at the ends.
Not a measurement; maker by maker.
Both have a page of their own. In full: Symphonium Meteor and Symphonium Triton. Every figure on this page comes from what Symphonium published, or is derived from it — what that maker publishes, counted.
