About the Phono Module
The Octave Audio Phono Module is a high-end, modular phono preamplifier designed for MM and MC cartridges with multiple interchangeable input and output boards. It combines a solid-state MC input stage with a tube-based RIAA/equalization stage using three tubes, and it can be configured as a phono stage or, with direct-drive output modules, as a full-function preamplifier capable of driving a power amplifier directly. Pricing varies by configuration; examples in current retailer listings place it around $6,000, while review-era configuration ranges ran roughly $5,400 to $7,500 depending on modules included.
