The Manley OASIS Phono Stage, successor to the legacy Chinook, introduces modern power supply and construction, marking a new era of high-fidelity preamplification from Manley Labs. Named after a cherished Mastering Studio partner, OASIS inherits the clean, precise audio circuits of the Steelhead and Chinook.


Key Features:

  • 6922 Triode Amplification: Each channel uses dual 6922 triode sections with low noise FETs, ensuring accurate and dynamic sound.
  • Passive RIAA Equalization: Restores the original frequency response with high precision.
  • No Integrated Circuits in Signal Path: Ensures pure, unaltered audio quality.
  • White Follower Output Stage: Provides super-low output impedance and robust current-driving capabilities, ideal for long cables and difficult loads.
  • Luxurious Chassis Design: Powder-coated over zinc passivated steel with smooth rounded edges and a CNC milled facia. Available in Manley Blue, Silver, or Black.


Easy Setup and Versatile Adjustment:

  • Gain Settings: Adjustable to 45dB, 50dB, 60dB, or 65dB, suitable for all Moving-Magnet and Moving-Coil cartridges.
  • DIP Switches: 31 input resistance options (26 to 800 Ohms plus 47k Ohms) and 7 capacitance settings (50 pF to 350 pF) for precise cartridge matching.


High-Quality Components:

  • Audiophile-Grade Parts: Time-proven reliability combined with Manley's dedication to seductive sonics.
  • California Crafted: Designed and built locally, emphasizing a clean, quiet signal path and exceptional linearity of vacuum tubes.


The Manley OASIS Phono Stage delivers accurate and musical reproduction of everything from exotic audiophile pressings to thrift-store classics. Simplify your listening experience and immerse yourself in the serene audio quality of the OASIS.
