The Campfire Audio Andromeda 2023 is 6.375Ω at 110.6 dB/mW; the Campfire Audio Chimera is 5.5Ω at 108.1 dB/mW. This page covers what they ask of an amplifier, not how they sound.
The Chimera needs 2.5 dB more than the Andromeda 2023 to reach the same loudness — 0.15 mW against 0.09 mW.
| Specification | Andromeda 2023 | Chimera |
|---|---|---|
| Impedance | 6.375 Ω | 5.5 Ω |
| Sensitivity | 110.6 dB/mW | 108.1 dB/mW |
| Sensitivity (voltage) | 132.6 dB/V | 130.7 dB/V |
| Power for 100 dB | 0.09 mW | 0.15 mW |
| Voltage for 100 dB | 24 mV | 29 mV |
| Current for 100 dB | 3.7 mA | 5.3 mA |
| Highest source impedance that leaves them alone (one-eighth rule) | 0.80 Ω | 0.69 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.
5 sources are low enough in output impedance for the Andromeda 2023 under the one-eighth rule but not for the Chimera (FiiO KA11, JDS Labs Atom+ (2nd gen), JDS Labs Atom Amp 2, 2 more).
9 sources stay below the audible-hiss threshold with the Chimera but cross it with the Andromeda 2023 (FiiO KA13, FiiO K11, Schiit Vali 3, 6 more).
280 of the 280 sources here reach 100 dB on both.
The Chimera is more demanding than 3% of the 567 non-electrostatic models in this database; the Andromeda 2023 than 1%.
| dB SPL | Andromeda 2023 power | Andromeda 2023 voltage | Chimera power | Chimera voltage |

| 85 | 2.8 µW | 4 mV | 4.9 µW | 5 mV |

| Source | Price | Headroom, Andromeda 2023 | Headroom, Chimera | Output impedance | Noise |
|---|---|---|---|---|---|
| JadeAudio JA11 | $20 | 18.4 dB | 15.2 dB | 0.5 Ω | 1.7 µV |
| FiiO BTR13 | $59 | 27.4 dB | 24.3 dB | 0.6 Ω | 1.0 µV |
| iBasso DC03 Pro | $69 | 23.5 dB | 20.4 dB | 0.12 Ω | 0.9 µV |
Of the 280 sources here, 280 reach 100 dB on both. 21 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 21 is the JadeAudio JA11, at $20. It leaves 18.4 dB of headroom on the Andromeda 2023 and 15.2 dB on the Chimera, its output impedance is 0.5 Ω against a one-eighth limit of 0.80 Ω and 0.69 Ω, and its noise figure puts the hiss floor 3 dB and 5 dB below the 20 dB SPL this site treats as the point where a quiet room stops hiding it.
| Model | As printed | Tolerance | Standard |
|---|---|---|---|
| Andromeda 2023 | 5-20 kHz | not printed | not printed |
| Chimera | 5-20 kHz | not printed | not printed |
Campfire Audio prints the same thing for both the Andromeda 2023 and the Chimera: 5-20 kHz.
Neither range has a tolerance printed beside it, so the matching numbers say little.
Not a measurement; maker by maker.
Both have a page of their own. In full: Campfire Audio Andromeda 2023 and Campfire Audio Chimera. Every figure on this page comes from what Campfire Audio published, or is derived from it — what that maker publishes, counted.
