At last, our favourite phono stage has been updated to operate with MANLEY POWER® which provides an even quieter blacker black background, yielding quicker sonic extremes over our older linear PSU designs. President EveAnna Manley recalls the moment she first made the comparison, “I brought a regular CHINOOK with its linear power supply, a stock unit, to Los Angeles to listen to it against a second CHINOOK that had been modified to work with our new MANLEY POWER® switch mode power supply.
My buddy Pete Lyman at Infrasonic Mastering spun up some vinyl records that he had cut the masters for on his lathe. Using his mastering studio environment, we were able to conduct a very precise comparative listening test between the two units. And even though we could not see which unit we were listening to, the sonic differences were unmistakable, and we both heard the same superiority in the new power supply design. I still can’t believe what a stunning technical and sonic accomplishment MANLEY POWER represents, and delivers as we adopt more of our designs to take advantage of our proprietary system.”
The OASIS Phono Stage offers an improvement in convenience over the older CHINOOK as the GAIN selections have been brought out from inside the chassis to the rear panel for easier access residing 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. Once you have set your GAIN and Loading for your cartridge, you’re done! Set it and forget it!
The OASIS sports an upgraded more luxurious chassis design while its efficient internal build keeps the price affordable. And like all Manley products, each OASIS Phono Stage is loyally handcrafted in the USA by American men and women at our Southern Californian factory located just 35 miles east of Los Angeles.
