The Arturia AudioFuse Rev2 is an audio interface at $599. It delivers 187 mW into 32Ω and 20 mW into 300Ω, which ranks it 165 of 280 for raw power among the sources in this database.
Measured at 100 dB SPL it has comfortable headroom on 521 of the 567 dynamic and planar headphones catalogued here, enough but not generous on 37, only marginal on 6 and not enough power for 3. The maker publishes a maximum output voltage but no power figure at any load, so every number here is an upper bound rather than a rating. Output noise is not published, so the hiss estimate cannot be run.
The manufacturer publishes a maximum output of 2.449 V but no power rating at any load. Every figure above is therefore a ceiling: the real output into a low impedance will be lower, possibly much lower.
Derived rows hold output voltage steady, as an amplifier does (method).

| Load | Power | Status | How it was arrived at |
|---|---|---|---|
| 32 Ω | 187 mW | Upper bound | the manufacturer publishes a maximum output voltage but no power rating, so this is a ceiling, not a rating |
| 150 Ω | 40 mW | Upper bound | the manufacturer publishes a maximum output voltage but no power rating, so this is a ceiling, not a rating |
| 300 Ω | 20 mW | Upper bound | the manufacturer publishes a maximum output voltage but no power rating, so this is a ceiling, not a rating |
| 600 Ω | 10.0 mW | Upper bound | the manufacturer publishes a maximum output voltage but no power rating, so this is a ceiling, not a rating |
Easiest to hardest to drive, with headroom at a 100 dB SPL peak.

The manufacturer does not publish an output noise figure for this source, so there is no hiss estimate here. If you have a measured figure, the hiss calculator takes it.
At 33Ω output impedance, the one-eighth rule says this source suits headphones of 264.0Ω and above. 545 of the 567 models here fall below that. That is most of the database, not a niche — 222 of them multi-driver in-ears, and the mismatch tilts the frequency response audibly rather than subtly.
| Source | Type | Price | Into 300 Ω | Output impedance | Output noise |
|---|---|---|---|---|---|
| FiiO KA11 | USB dongle | $29 | 22 mW | 0.7 Ω | 1.7 µV |
| FiiO BTR13 | Bluetooth receiver | $59 | 10.0 mW | 0.6 Ω | 1.0 µV |
| FiiO KA3 | USB dongle | $79 | 14 mW | 0.5 Ω | 1.7 µV |
Of the 280 sources here, 53 do everything the Arturia AudioFuse Rev2 does as a headphone output: reach 100 dB on every headphone it reaches and stay inside the one-eighth rule wherever it does. The cheapest of them is the FiiO KA11 at $29, against this one’s $599 — $570 less, and a USB dongle rather than an audio interface.
The cheaper one also publishes a noise figure, which the Arturia AudioFuse Rev2 does not — so on the paperwork it is ahead, not merely level.
This counts the headphone output only; inputs, converters, the volume control and the build are outside it.
