Does the Schiit Valhalla 2 drive the HiFiMan Edition XS?

Computed from measured specifications · target SPL 110 dB · load 50 Ω

Verdict

Adequate

The Schiit Valhalla 2 adequately drives the HiFiMan Edition XS with limited margin (~4.4 dB headroom at 50 ohms; needs ~66.1 mW, delivers 180 mW). Note: this OTL tube amp's high output impedance (14 Ω) interacts strongly with this low-impedance (14 Ω) headphone, which can audibly alter its tonal balance. OTL tube amps are best paired with high-impedance (250 Ω+) headphones; this is a less ideal match.

Power source Manufacturer
Schiit Valhalla 2 manufacturer spec (Audiophonics retailer, citing Schiit official): 180/800/450 mW at 50/300/600 Ω. OTL/hybrid topology: more power into 300 Ω than 50 Ω (normal for OTL). Output impedance 14 Ω (hi-gain) / 3.5 Ω (lo-gain) from Schiit PDF manual and Schiit Europe. Using 14 Ω as worst-case for damping check. · Source ↗
Impedance caution

This OTL tube amp's output impedance (14 Ω) is high relative to this headphone's 14 Ω impedance (ratio 1.0×). OTL tube amps are best paired with headphones ≥ 250 Ω; this combination may cause audible tonal coloration.

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.
