I wanted to experiment with SET amps as my only reference with modern tube amps are my Atmasphere MA-1s, tried the Dennis Had PSET amps and the venerable Almarro 318B, I know these are not the typical definition of SETs like the 300Bs and such, what I found was that even with my 95 dB sensitivity speakers the amps (as Ralph wisely explained) due to their 18W relatively low power were making distortion after 50 percent gain, tried differently tubes to gain every extra watt possible but really nothing to be done so I kept my Atmasphere and sold the amps. I'm sure the results with 100 plus dB sensitive speakers will be different and these amps are very good, both of them, the Dennis Had is really a tube rolling dream. Going back to my point, at least to my inexperienced ears without the reference set by the Atmasphere monos I wouldn't be able to recognize the distortion at higher levels made by the SETs.
Maybe one day I can get higher sensitivity speakers and try SET again but really having an Amp with the "elasticity" of powering a wide range of speakers is paramount to me.
Thank you Ralph for the education on this post, many will say and argue that you don't know what you're taking about and even like the OP said I had to get my glasses to understand maybe 60 percent of what you're saying (and I'm being generous to myself) what you are saying reflects my empirical results.
