Experience the Manley Oasis, reference-grade vinyl reproduction
The Manley Oasis Phono Stage represents the evolution of the acclaimed Chinook design, incorporating proprietary Manley Power® supply technology for exceptional noise floor performance and dynamic resolution. Hand-assembled in California, the Oasis combines cascaded 6922 dual triode gain stages with precision passive RIAA equalization to deliver accurate frequency response and transparent amplification. Engineered for both Moving Magnet and Moving Coil cartridges, the Oasis provides comprehensive setup flexibility with exceptional sonic fidelity.
Dual triode topology with White Follower drive architecture
The Oasis employs cascaded 6922 dual triodes throughout the gain stages, coupled with a White Follower output driver for exceptionally low output impedance and superior linearity. This all-tube topology maintains signal integrity from input to output while the passive RIAA equalization network ensures accurate frequency compensation across the entire audio spectrum. The design prioritizes transient accuracy, phase coherence, and tonal neutrality for faithful vinyl reproduction.
Comprehensive cartridge matching with accessible rear-panel controls
All gain and loading adjustments are configured via rear-panel DIP switches for convenient setup and system integration. Four selectable gain settings spanning 45 dB to 65 dB accommodate virtually all Moving Magnet and Moving Coil cartridge types. Thirty-one resistive loading options from 26 Ohms to 800 Ohms, plus 47k Ohms, combined with seven capacitive loading selections, enable precise impedance matching for optimal cartridge performance and frequency response accuracy.
California craftsmanship with precision CNC machining
Hand-assembled at Manley's Southern California facility, the Oasis features a CNC-milled aluminum faceplate and robust chassis construction for long-term reliability. Premium components throughout the signal path ensure low noise operation and extended service life. The Oasis embodies Manley's commitment to vacuum tube phono amplification, delivering the dimensional imaging and harmonic accuracy that define reference-grade vinyl playback systems.
