Octave Phono Module

The Octave Phono Module was created for the most ambitious analog listeners seeking both sonic refinement and system flexibility. Drawing on more than three decades of experience in tube preamplifier design, Octave developed a modern hybrid phono stage that combines the tonal richness of tubes with the precision and noise control of solid-state circuitry.

At its heart, the Phono Module employs an advanced electronic MC input stage—eliminating the need for traditional step-up transformers, which are often limited in load impedance and prone to interference. This design achieves outstanding signal-to-noise performance, ensuring even low-output MC cartridges deliver their full musical potential. The RIAA stage itself is tube-based, derived from Octave’s highly regarded HP 500 SE, and uses three tubes to achieve the gain required for precise equalization.

The system’s modular design allows for up to three input modules (RCA MM, RCA MC, or balanced XLR MC) to be installed simultaneously, each with adjustable impedance and gain settings. Output flexibility is equally advanced, with interchangeable modules offering dual RCA outputs, single-ended Direct Drive, or a balanced XLR Direct Drive stage. These modules allow the Phono Module not only to function as a world-class phono stage but also to drive a power amplifier directly when desired.

With its separate external power supply, soft-start electronics, and Octave’s hallmark reliability, the Phono Module is built for both performance and longevity. Its ability to combine modular adaptability, cutting-edge hybrid design, and the musical warmth of tubes makes it one of the most complete and versatile phono preamplifiers available today.
