Swiss company Orpheus Lab is preparing two premieres for High End Vienna 2026. At the event, the company will present the flagship Orpheus Lab H Three M1400 Opus II monoblock power amplifiers, as well as the Orpheus Lab A Four N200 integrated network amplifier. Both models are aimed at the High End segment and are intended to demonstrate the further development of the brand’s proprietary amplification technologies.

The Orpheus Lab H Three M1400 Opus II monoblock power amplifier belongs to the Heritage series and uses a high-bias Class A/AB circuit. Each monoblock is equipped with a 2400 VA power supply and is designed to work with loudspeakers that require a serious reserve of power and current. The claimed output is 700 W into an 8-ohm load, 1,400 W into 4 ohms and 2,300 W into 2 ohms.

The output stage of the H Three M1400 Opus II uses 48 hand-matched MOSFET transistors. The amplifier’s peak current reaches 192 A, underlining its focus on controlling demanding loudspeakers and maintaining stable operation with low-impedance loads. The bias current is 2,000 mA, while idle power consumption reaches approximately 520 W.

To handle this level of heat dissipation, Orpheus Lab has used a large aluminium chassis designed for efficient heat removal and stable thermal performance. Each monoblock weighs 135 kg and measures 570 × 748 × 345 mm. Judging by its specifications, the H Three M1400 Opus II is aimed at large high-end systems where not only high power but also substantial current reserves are required.

The second premiere will be the Orpheus Lab A Four N200, an integrated network amplifier based on the A Four I200 model. The new product retains the dual-mono amplification architecture, but adds expanded digital and streaming functionality. The amplifier delivers 200 W per channel into 8 ohms and is equipped with two 880 VA toroidal transformers.

For source connectivity, the A Four N200 offers Ethernet, USB, AES/EBU, coaxial S/PDIF and optical inputs. The unit supports Qobuz Connect, Tidal Connect, Spotify Connect, UPnP and Roon, allowing it to serve as the central component of a modern digital audio system. It also includes balanced XLR preamp outputs for connecting a subwoofer and a home cinema bypass mode for integration into a home theatre setup. The digital section is built around an ESS Technology ESS9028PRO DAC and the company’s proprietary FPGA architecture, inherited from the CD players of the flagship Absolute Line.
Shipments of both models are expected in autumn 2026. In the UK, a pair of Orpheus Lab H Three M1400 Opus II monoblocks will cost £153,000, while the Orpheus Lab A Four N200 integrated amplifier is priced at £23,900.
