Tellurium Q Iridium Phonostage: Reference MM/MC Phono Stage with Adjustable Output
The Tellurium Q Iridium Phonostage is a high-performance phono stage designed to meet the demands of the most discerning audiophiles, offering full compatibility with both moving magnet (MM) and moving coil (MC) cartridges. With separate circuitry and adjustable gain, it delivers extremely quiet and precise conversion of turntable signals to line level.
Its internal architecture includes a dedicated buffer stage for MC cartridges, minimizing noise and maximizing musicality, along with independently volume-controlled outputs, allowing direct connection to power amplifiers or integration with preamps lacking a phono input. The regulated power supply, featuring a 30 VA toroidal transformer and high-capacity capacitors, ensures clean and stable power delivery.
A perfect match for high-end systems that demand accuracy, dynamics, and natural vinyl reproduction.
