WES is an uncompromised design, featuring EL34, 6SL7, and 5AR4-5U4GB rectifier.
All-triode drive, fully balanced. Two units design - AMP unit and Power Supply unit with dual power switch. Innovative stackable chassis with exposed tubes. A standard unit now build with 2 STAX headphone outputs. The HE90 output is optional.
Fully balanced topology
Peak-peak voltage swing: 1300 volts
Stax PRO bias: 580V
Sennheiser HE90 bias: 500V
* Dual power switch
Standard chassis size
Removable glass panel
PSU: 4.5"(H), 16.5"(W), 12"(D)
AMP: 7.5"(H), 16.5"(W), 12"(D) (with tube guard)
Weight (AMP + PSU): 40 pounds or 18.2 kg
* From a cold start, the dual power switch protects the tubes from a high current surge. Turning on just one of the power switches provides low voltage to the heaters while the unit remains in stand-by mode. Turning on both power switches allows the unit to function properly.
