ORIA – PURE CLASS A OTL HEADPHONE AMPLIFIER

The Oria headphone amplifier operates in pure Class A using an OTL (Output Transformer-Less) topology. Each channel employs a dedicated EL34 output tube operating without output transformers, providing faster transient response, lower coloration, improved harmonic integrity, superior spatial realism, enhanced microdynamic resolution, and wider bandwidth.

By eliminating output transformers, the design avoids the magnetic limitations commonly associated with conventional tube amplifiers, resulting in a more transparent, natural, and direct musical presentation. The entire amplification stage operates exclusively in the analogue domain and without global negative feedback.

INTEGRATED HIGH-RESOLUTION MUSIC SERVER

This system features a fully integrated high-resolution music server derived from the architecture of the MS-01 Music Server. It provides high-resolution streaming, local music library playback, NAS compatibility, Internet radio, USB playback, Volumio Premium integration, network streaming (including TIDAL Connect and Qobuz Connect), and multi-room capabilities.

The server has been engineered to operate seamlessly with the analogue headphone amplification stage, minimizing unnecessary interfaces, signal degradation, and noise contamination. The integrated DAC is based on the ESS Sabre ES9038Q2M architecture and supports PCM decoding up to 768 kHz and DSD512.

To maximize sonic performance, the digital section employs independent analogue and digital power supplies, minimizing interference between the two domains.
