I'm from South Korea. I saw this review of the S.E.X, was initially daunted by the idea of soldering and assembling electronic components, but was ultimately persuaded to get myself one. He doesn't talk much about subjective sound, but does demonstrate harmonic distortion (particularly the 2nd harmonic that extends to higher frequencies well). I've been reading up about SET design, and am quite intrigued at how much there is to know about audio amplification. Hopefully, all this will build up to greater appreciation for music.
