The KWA 100 provides the strengths of both tube and solid state products: 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. The heart of the KWA 100 Amplifier is a single voltage gain stage called the “Solid State Music Stage.” The circuit was developed by Alan Kimmel, creator of the exceptional vacuum tube “Mu” stage. Mosfet output stage design.

Features include: high-low bias switch, and true balanced floating inputs, accepting balanced and unbalanced inputs. The design incorporates a regulated power supply for the input stage, and oversized heat sinks. The first watts operate in pure Class A. The KWA 100 uses no global feedback, is direct-coupled, fully differential, and designed and Handmade in the USA.
