General Information
The Gilmore Electrostatic Headphone Amplifier (KGSS) is HeadAmp's solid-state electrostatic amplifier. This current-domain design by Kevin Gilmore drives all Stax headphones as well as Sennheiser Orpheus electrostatic phones with a special connector, available by request.
The amplifier is housed in a sophisticated brushed aluminum enclosure that is available in black or silver. A balanced input and unbalanced input can be connected to the amplifier and selected by a switch. A pair of DACT stepped-attenuator volume controls are standard in the KGSS as are the custom machined knobs.
A custom-made toroidal transformer feeds the dual high-voltage power supply that the KGSS runs off of. A separate 580 Volt supply provides the bias voltage for the electrostatic headphones.
The KGSS provides extremely detailed, transparent sound to your electrostatic headphones. Only the highest quality components are used throughout the construction of this amplifier.
