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.
What the HD 560S needs
| Spec | Value | Why it matters |
|---|---|---|
| Impedance | 120 Ω | Easy-ish load, but damping still matters |
| Sensitivity | 110 dB/V | How loud per unit power |
| Power for 110 dB peaks | ~8.3 mW | Transient headroom for positional cues |
| Amp output impedance | ≤ 15 Ω ideal | The 8:1 damping rule — keeps the tuning flat |
Sound character — footsteps, general use & music
| Axis | Grade | What it means |
|---|---|---|
| Footsteps (positional) | 5/5 | The ONLY competitive axis — and it saturates: any clean open-back clears the bar, so more above baseline buys little advantage. |
| General use | 4/5 | All-round daily versatility — comfort/preference, not a competitive edge. |
| Music | 4/5 | Tonal enjoyment — preference, never advantage. |

"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.
