Lynx Aurora(n): power output and what it will drive

The Lynx Aurora(n) is an audio interface at $3499. It delivers 1.3 W into 32Ω and 138 mW into 300Ω, which ranks it 67 of 280 for raw power among the sources in this database.

Measured at 100 dB SPL it has comfortable headroom on 561 of the 567 dynamic and planar headphones catalogued here, enough but not generous on 5 and only marginal on 1. 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 impedance is not published. Output noise is not published, so the hiss estimate cannot be run.

The manufacturer publishes a maximum output of 6.443 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.

Derivation holds output voltage steady between and beyond the published loads rather than output power, because that is what an amplifier actually does. The full method is written up here.

Ordered from easiest to hardest to drive. Headroom is measured at 100 dB SPL, which is louder than almost anyone listens — a small negative number means the source still plays loud, just without reserve for peaks.

These figures come from each manufacturer's own sensitivity rating. A handful of planars — the HiFiMAN Susvara and the Abyss AB-1266 in particular — are widely reported to need far more than their published sensitivity implies, so treat a bare pass on those as optimistic rather than settled.

The manufacturer does not publish an output noise figure for this source, so the hiss estimate that runs on every other page here cannot be run on this one. Rather than substitute a plausible number, this page leaves the question open.

If you know the noise figure from a measurement you trust, the hiss calculator takes it directly and tells you where that noise lands in your own in-ears.

The manufacturer does not publish an output impedance for this source. That is the one number that decides whether it leaves your headphones alone or acts as a tone control, so its absence matters more than it looks: without it, nothing here can tell you how this source will behave with a multi-driver in-ear.

If you find a measured figure you trust, the checker will work out the consequence for any headphone.

Of the 280 sources here, 79 do everything the Lynx Aurora(n) does as a headphone output: reach 100 dB on every headphone it reaches. The cheapest of them is the Schiit Magni Heresy at $99, against this one’s $3499 — $3400 less, and a desktop amplifier rather than an audio interface.

The cheaper one also publishes an output impedance, which the Lynx Aurora(n) does not — so on the paperwork it is ahead, not merely level.

This counts a headphone output and nothing else. Inputs, converters, microphone preamps, balanced outputs, the volume control, the case and the warranty are all outside it, and any of them can be the reason to buy the dearer box. What the count does say is that the three numbers a maker can be held to do not separate them.

Worked out in advance against its closest rivals: vs Audient Horizon 8P · vs Audient ORIA · vs RME Fireface UFX II · vs RME Fireface UFX III. Each of those pages lists the headphones that tell the two apart.
