Uses a 2 x 6922 gain stage and 2 x 6922 output stage\u003c\/h3\u003e\n\u003cp\u003eOne of ours and Manley's and our customers' favorite phonostages the Manley Chinook has been updated for 2024. The new Oasis uses Manley Power, a high-end switching supply that provides an even quieter blacker black background, yielding quicker sonic extremes over our older linear PSU designs.\u003c\/p\u003e\n\u003ch4\u003eWith Upscale Special Tubes\u003c\/h4\u003e\n\u003cp\u003eJust as we did with the Upscale Audio edition of the Chinook, all our Oasis inventory comes with upgraded tubes, exclusive to Upscale Audio. Manley takes out the stock EH 6922's, and replaces them with Upscale Audio graded and tested Gold Lion 6922. This is done at the factory, so you're still getting a factory-sealed piece here, don't worry. This tube garnered great feedback from Chinook owners, so we knew it'd be a lovely tradition to carry on with the Oasis.\u003c\/p\u003e\n\u003ch4\u003eMore On the Oasis\u003c\/h4\u003e\n\u003cp\u003eThe Oasis sports an upgraded more luxurious chassis design while its efficient internal build keeps the price affordable. And like all Manley products, each Oasis phonostage is loyally handcrafted in the USA at Manley's Southern Californian factory not far from us at Upscale Audio.\u003c\/p\u003e\n\u003cp\u003eThe gain settings are on the rear panel next to the resistive and capacitive loading DIP switches. There are tons of loading options to mate with any moving coil or moving magnet cartridge.\u003c\/p\u003e\n\u003cp\u003eLike the Steelhead, each channel employs the two triode sections of a 6922 for amplifying duties assisted by low-noise FETs receiving the signal below each cathode. Highly accurate passive RIAA equalization networks perform the decoding task to restore the originally intended frequency response to the audio signal. In the Oasis, the signal passes through no integrated circuits. There are ICs deployed in a servo configuration to apply a precise biasing voltage to the gate of each FET, and you might notice some other chips for logic functions. Importantly, the signal is directly coupled from the gain stages to another 6922 dual triode serving as the output driver in a White follower configuration. This output stage circuit is Manley's favorite because of its super-low output impedance and beefy current-driving capabilities. It can drive long cable lengths and difficult loads, tube or solid-state. Bring it on. No wimpy cathode followers here!\u003c\/p\u003e\n\u003cp\u003eThe chassis is a new powder-coated over zinc passivated steel design with a large-radiused substantial top cover sporting smooth rounded side edges. Rounding out the casework, the frontal face is adorned by a 3\/8” thick CNC-milled facia with an intricately inlaid contrasting “racetrack” insert for visual interest. \u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e6922 x 2 (gain stage) plus 6922 x2 (output stage).
