VFET amplifier "Mercury"
This amplifier utilizes VFET (Vertical Channel Field-Effect) transistors known to have similar characteristics as vacuum tubes.
This amplifier was first ment to be used with power demanding planar magnetic headphones like Audeze, but it showed very nice capability of 2x15W class-A also to drive loudspeakers.
The amplifier is usable as power amplifier or stand alone due to inner volume potentiometer.
And yes, there is this certain fluidum about those VFet's: sound is smooth and fluvial like mercury.
