Looking for a new Amp or Preamp? If you're after tubes, post over here.

RE: At best Cheever defines the euphonic, not the accurate

Because it does. My ears tell it like it is and the best reason beyond that I can give you is that the distortion is primarily 2nd and 3rd order harmonics with no really high order harmonics. This means it is basically inaudible or do you not "believe" in the research behind psychoacoustics? Furthermore, KR is one of the few SET manufacturers that uses a properly specified output transformer that keeps bass distortion very low and thus eliminates the "tubey" coloration you are probably equating with "tube" sound.

If you ever get a chance, listen to a good OTL amp from Atma-sphere for example. You will realize that tube amps without the output transformer are lightening fast with deep tight bass and not a scotch of "tubey" coloration. It is the output transformer, not the tubes.

Finally, as far as a low frequency linear amplifier, the triode tube is still the closest to linear of ANY amplification device. Your beloved bipolar transistors are the LEAST linear...period! This is an incontrovertible fact... If you want to discuss other applications and suitability then we can but for an audio frequency amplifier triodes are NOT obsolete.
