The H Three M800 Opus II is a mono power amplifier from Orpheus Lab, sitting below the flagship H Three M1400 Opus II with exceptional signal-to-noise performance and a remarkable damping factor. The H Three M800 Opus II brings Orpheus Lab's meticulous engineering to dedicated monoblock power amplification.
Key specs that matter
Output power is 800W into 4 ohms. Frequency response spans 5Hz to 90,000Hz within plus-or-minus 3dB. Signal-to-noise ratio reaches an exceptional 123dB, with total harmonic distortion plus noise at an exceptionally low 0.0018% with full global feedback, maximum power consumption at 1,200W, and a remarkable damping factor exceeding 1,100. At 440 x 420 x 271mm and 56kg, the H Three M800 Opus II represents a serious monoblock commitment reflecting Orpheus Lab's uncompromising Swiss build standards.
Sound and use context
Expect substantial power delivery combined with exceptionally clean measured performance reflecting the extraordinary 123dB signal-to-noise and near-immeasurable 0.0018% distortion figures, consistent with Orpheus Lab's broader uncompromising engineering philosophy.
Pairing
The remarkable damping factor exceeding 1,100 suits demanding, revealing loudspeaker loads directly, and Orpheus Lab's own H Two 33BD Opus II preamplifier shares the brand's coherent engineering philosophy.
Alternatives
Orpheus Lab's own flagship H Three M1400 Opus II offers a considerably more powerful alternative for buyers wanting Orpheus Lab's absolute current flagship engineering.
