Modwright KWA 150 Signature Edition Amplifier

Some background info:

The KWA 150 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 150 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.

Features include: high-low bias switch, stereo/bridge-mono switch and true balanced floating inputs, accepting balanced and unbalanced inputs. The design incorporates a regulated power supply for the input stage, Cardas best connectors and oversized heat sinks. The first watts operate in pure Class A.

The KWA 150 uses no global feedback, is direct-coupled, fully differential, dual-mono, bridgeable, and designed and built in the USA.

We have taken the KWA 150 and applied nearly two years of additional R&D and further thought into how to FURTHER improve upon the award-winning KWA 150.

The Absolute Sound “To my ears, the KWA 150 represents a smashing success, combining the musicality of tubes with the punch, power delivery, and bass reach of transistors. Factor in the performance and looks of this amp relative to its asking price and the result is a fantastic value. Kudos to ModWright for delivering the sonic goodies, while avoiding sticker shock. Buyer beware: Once auditioned, this amp is hard to walk away from”
