About the Orpheus Mk3
The Thrax Audio Orpheus Mk3 is a high-end, tube-based phono preamplifier with passive LCR RIAA equalization. It is a later revision of Thrax’s Orpheus design, intended to accommodate both moving-magnet (MM) and moving-coil (MC) cartridges, with selectable gain and loading, balanced and unbalanced connections, and configurable phase and grounding. A dealer describes the Mk3S revision as introduced in 2022 with power-supply and component updates; a 2023 report identifies an Orpheus Mk3.
