Does the iFi Zen DAC V2 drive the Beyerdynamic T1 (3rd Gen)?

Computed from rated specifications · target SPL 110 dB · load 600 Ω

Marginal

The iFi Zen DAC V2 marginally drives the Beyerdynamic T1 (3rd Gen); barely reaches target SPL (~2.6 dB headroom at 600 ohms; needs ~10.0 mW, delivers 18 mW). (Amp power at 600 ohms is estimated from its published figure at a nearby load.) Note: output impedance for this amp isn't reliably published, so the damping interaction into this 600 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 600 Ω headphone cannot be assessed. Treat low-impedance pairings (below ~80 Ω) with caution.

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.

Power figure note

The amp's power at 600 Ω was not published directly — it was derived from the voltage ceiling at a published lower-impedance load. The actual delivered power may differ modestly.
