First, I am really surprised that no one is talking about this rather interesting amp on this forum...is it just because no one has heard it? I heard it in Munich and thought it quite good.
What I find most interesting is that in many ways it measures like a good SET, with a linear (Log/log scale) increase in distortion with increasing power. Also, that it has a slight upturn in distortion in the bass...not sure where that is coming from (interstage transformer perhaps?) as it doesn't have an ouptut transformers being SS output. The distortion content is largely monotonic, like a good SET and the IMD spectrum also looked similar to a lot of SETs. Clearly the amp is free or nearly free from negative feedback. It reminds me of a SoundStage measurment of the Monarchy Audio M250 monos, which were also feedback free hybrids that had quite similar measurments (but were less than 1/10th the price).
I also think that Mr. Fremer's remarks about this amp show that in many ways it shows up his Dartzeels giving him some of the best sound he has ever heard in his system.
Thoughts?
