Product Description

Modwright KWH 225i Integrated Amplifier

Hybrid Integrated Amplifier


modwright kwh 225i

Hybrid Design In Modwright's DNA

The Modwright KWH 225i hybrid integrated amp represents the culmination of years of solid state and tube preamp/amplifier design. Modwright has from it's very beginning preferred a hybrid approach to system building. Combining the natural richness of tube preamplifiers with the grip and punch of solid state amplification.

The KWh 2225i hybrid integrated amp is a natural extension of this philosophy. Combining the solid state output stage of Modwright's Reference KWA 150SE amp, with the controls and integration of the KWI 200, then replacing the KWI 200 solid state preamp circuit with a Class A tube design and increasing the power to 225W. The result is the KWH 225i. 

Class A Operation, Zero Negative Feedback

The Class A preamp stage, with 25 watts of zero negative feedback Class A output from the amplifier section will be a fantastic match for efficiency speaker designs. Even lower efficiency speakers will benefit from the high current 225 watts of Class A/B output.
