Does the iFi Zen DAC V2 drive the HiFiMan Arya?

Computed from measured specifications · target SPL 110 dB · load 32 Ω

Adequate

The iFi Zen DAC V2 adequately drives the HiFiMan Arya with limited margin (~9.4 dB headroom at 32 ohms; needs ~32.0 mW, delivers 280 mW). Note: output impedance for this amp isn't reliably published, so the damping interaction into this 28 Ω load can't be assessed; treat low-impedance pairings with caution.

* Loads marked "est." are derived from the published voltage ceiling at a lower-impedance load (V = √(P·R) → P_higher = V²/R_higher). All derivations are upward only.
iFi Zen DAC V2 SE output: 280 mW @ 32 Ω, 36 mW @ 300 Ω (iFi tech lowdown PDF and product page). Output impedance: conflicting sources (manufacturer PDF cites '≤100 Ω unbalanced' which may refer to RCA pre-out, not the headphone jack; likely <<1 Ω for headphone output but unconfirmed). Set null; damping check flagged as indeterminate. 600 Ω derived from 300 Ω. · Source ↗
Impedance — unknown output impedance

This amp's output impedance is not reliably published, so the damping interaction into this 28 Ω headphone cannot be assessed. Treat low-impedance pairings (below ~80 Ω) with caution.

Planar driver note

Planar-magnetic headphones can have high current demands that are not fully captured by the power headroom model. Even with adequate headroom, some solid-state amps may struggle to deliver sufficient peak current for transient dynamics. Prefer amps rated for low-impedance planars.

Specification confidence: low

One or more amp specifications (power output or output impedance) are estimated rather than published by the manufacturer. Treat this pairing's verdict as approximate.
