Had does go on about the 2nd order harmonics inherent in this amp, and regarding "dogma," the entire SET (or SEP in this case) world has its own dogma it seems, and I'm all for it as it's a thing that has transformed my thinking about such things (although I've used relatively low wattage guitar amps for many years…including a hand made single ended amp with a tube rectifier). Regardless of all that, this amp "seems" to have less distortion of ANY kind at even louder levels, and the openness and apparent clarity may be the amp simply fooling me, which as long as I like the results is just fine. As Fremer said in a recent article, "my hearing gets worse, but my listening gets better," which certainly applies to my old person self as I continue to produce and mix concerts and play music. Had's new stuff since retiring from Cary seems like an assault on convention (and pricing), and if he makes a remote preamp I'm in with one of those too! Note no measurements are around for the Fire Bottle amp unless somebody else has tested one, but Had certainly measures things and his idea of what sounds good might just be the same as mine.
