Best DAC/amp for the Sennheiser HD 560S

The Sennheiser HD 560S is a 120Ω open-back pair. To hit clean 110 dB transient peaks — the headroom that keeps footsteps and gunfire punchy, not just loud — it needs about 8.3 mW into that load. The pick that does it most affordably is the Schiit Magni Unity.

AxisGradeWhat it means
Footsteps (positional)5/5The ONLY competitive axis — and it saturates: any clean open-back clears the bar, so more above baseline buys little advantage.
General use4/5All-round daily versatility — comfort/preference, not a competitive edge.
Music4/5Tonal enjoyment — preference, never advantage.

DAC/amps ranked for the HD 560S

The 8:1 damping rule
For tight, neutral bass the headphone's impedance should be at least the amp's output impedance (Zout). Below that, a high-Zout source loses control of the driver — bass bloats and the frequency response shifts with the load. AimBench checks this ratio as a pass/fail sufficiency gate, not a graded score.

"Headroom" is power available vs the ~8.3 mW needed for 110 dB peaks (more = cleaner transients). "Damping" is the headphone impedance ÷ amp output impedance — at least 8:1 keeps the frequency response flat. Specs are sourced; the target SPL and 8:1 rule are the declared model.

The pick: Schiit Magni Unity

For the Sennheiser HD 560S, the Schiit Magni Unity delivers ~884 mW into 120Ω (+20 dB of headroom) at a 1200:1 damping ratio — clean, loud, and tonally neutral. It's the most cost-effective amp here that drives these without compromise.
