Revelatory? – It's a question asked by Spatial Audio's new Revelation series tube gear designed by Don Sachs and Lynn Olson. The $20K/pr 300B monos propose 25 watts of class A triode power from a fully balanced signal path with 200W linear power supplies of 130dB noise isolation. A Cinemag input transformer handles phase splitting, another Cinemag transformer interstage coupling between the 6SN7 inputs and KT88 drivers. A Monolith push/pull output transformer wires to 8/4Ω tabs. The $5K matching preamplifier is another fully balanced design with Khozmo resistor-ladder remote-controlled volume and 6SN7 gain stage.
