ModWright KWA-100

The KWA 100 is ModWright’s 100-watt @ 8ohm stereo power amplifier, employing a fully discrete, single voltage gain stage circuit that ModWright calls a “Solid State Music Stage” (developed by Alan Kimmel), along with a Mosfet output stage. The design objective for the amplifier was to combine the strengths of both tube and solid-state amplifier designs. According to ModWright, the solid-state music stage produces, “3-D sound-staging, holographic imaging, and a beautiful midrange of tubes, combined with sparkling highs, low distortion, bass resolution, and control of solid state.”
Other key features of the KWA 100 amplifier include a high-low bias switch; true balanced floating inputs accepting balanced and unbalanced input connections; a regulated power supply for the input stage; oversized heat sinks; and Class A-B operation, with the first watts of power produced in pure Class A.
