Alamandog:
Saw your post here and the other one about the PH150. I have only heard the PH150 in show conditions so chose not to post on the other thread but I have owned a KWA150SE for several years now and have been extremely happy with the amp. Prior to the Modwright I owned a series of Audio Research solid state amps (100.2, 150.2 and SD135) all were nice amps in their own right but none presented the music in as realistic fashion as the Modwright. To my ears the KWA150SE strikes a wonderful balance of having some tube attributes (slight warmth, no edge, holographic, musically refined) and the best of solid state designs (authority, quiet, bass heft, reliability). The Modwright is built like a tank and will last forever. Though I have not heard it in direct comparison with a large number of other amps, many who have consider it a reference caliber product. I suspect they are correct. If you are considering one, I would recommend it without hesitation. The only thing that would cause me to part with my KWA would be to go in an entirely different direction--like SE tube monoblocks--which would also work in my setup. (Dan's new 845 monos have certainly caught my attention!). Best of luck with your journey!
