The H Three M1400 Opus II is an extraordinary flagship mono power amplifier from Orpheus Lab, built with staggering output power and considerable mass. The H Three M1400 Opus II represents Orpheus Lab's most ambitious current statement in power amplification.
Key specs that matter
Output power is a staggering 700W into 8 ohms, doubling cleanly to 1,400W into 4 ohms - a textbook power doubling indicating a robust, well-regulated power supply. At 570 x 748 x 345mm and a substantial 135kg, the H Three M1400 Opus II represents one of the most considerable monoblock commitments available anywhere, reflecting Orpheus Lab's absolute flagship engineering ambition.
Sound and use context
Expect extraordinary power delivery reflecting the staggering 700/1,400W output and clean power doubling into 4 ohms, representing Orpheus Lab's absolute current flagship monoblock engineering ambition.
Pairing
The staggering power output combined with the clean power doubling into 4 ohms suits the most 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 H Three M800 Opus II offers a considerably more accessible monoblock alternative within the same broader amplifier catalogue.
