So my conclusion is it doesn;t seem like this new amp is anything radical at all, just an application of well known theory (i mean damping factor on loads) with a marketing twist!(not that i'm decrying it or anything). It seems that 6moons is marketing (reviewing) it with a vengeance.

I'm not sure about the relative impacts of damping factr sensitivty versus the even order distortion on perceived euphonia. That would require some research...it seems you have more empirical data here than i do. However, i will offer that in order to understand why tube amps sound different from ss, we may need to start with a list of factors, two of which would undoubtedly be DF & Distortion. there may be other factors too, such as pshoacoustical factors, and then the other factors that may not have been quantified yet (the elusive "tone").

Anyways, nice post. thanx
