The KWH 225i represents the culmination of years of SS and tube preamp and amplifier design. Our preferred approach has always been that of a hybrid system. The KWI 200 SS integrated amp was a big success for us, offering excellent performance and integration. The KWH 225i takes things to the next level. We combined the solid state output stage of our Reference KWA 150SE amp with the controls and integration of the KWI 200 and a tube preamp stage. We then increased the power to 225W. The result is the KWH 225i. We think you’ll like it! KWH 225i Integrated KWH 225i Hybrid Integrated The KWH 225i represents the culmination of years of SS and tube preamp and amplifier design.
