Does the Little Dot MkII drive the Beyerdynamic T1 (3rd Gen)?

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

Ample

The Little Dot MkII drives the Beyerdynamic T1 (3rd Gen) with ample headroom (~11.8 dB headroom at 600 ohms; needs ~10.0 mW, delivers 150 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.

Little Dot MkII SEPP OTL circuit. Power figures (100/200/300 mW at 32/120/300 Ω) appear consistently across retailer listings (Linsoul, ShenZhenAudio) citing manufacturer spec. Note unusual characteristic: more power into 300 Ω than 32 Ω — typical for OTL amps. Output impedance not published; SEPP OTL topology suggests ~20–50 Ω but no reputable non-forum measurement found. 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.
