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 compatibility

This OTL tube amp's high output impedance (14 Ω) is a good match for the Philips SHP9500's 32 Ω impedance. The impedance ratio (2.3×) falls within the recommended range for high-output-impedance tube sources — a classically well-matched pairing.
