ModWright KWH 225i Hybrid Integrated Amplifier

ModWright didn't design the KWH 225i by adapting a conventional integrated amplifier. They built it by combining three things they already knew worked: the output stage architecture of the Reference KWA 150SE amplifier, the control integration of the KWI 200, and a Class A tube preamplifier stage where a solid-state preamp circuit had been. Then they increased the power to 225 watts.

The Architecture

The KWA 150SE's output stage is the foundation — MOSFET devices in a topology that was developed for ModWright's reference-level amplification without compromise. That output stage is now driven by a tube preamplifier operating in Class A, providing the harmonic richness, spatial dimensionality, and naturalness that defines ModWright's tube-influenced design philosophy. Zero global negative feedback throughout.

225 watts into 8 ohms. Enough power to drive virtually any speaker with authority, combined with the tube input stage's musical character. The integration is not a compromise — the tube and solid-state sections were designed to work together from the beginning.

Press Recognition

ModWright has been reviewed by The Absolute Sound, Stereophile, and Hi-Fi+ over many years. The KWH 225i has been covered as the integrated that makes the ModWright sound accessible in a single chassis.
