Saxo, I apologize. However, I do own a pair of Atma Sphere M60 monoblocks.
Wellfed, yes it was the Paul Speltz Zero Autoformers I tried in my system. For about 1.5 months, on loan from a good friend, whose testimonial is on the website. Beginning with the 2X setting, and also with some higher multiplication configurations.
I do not deny that in your situation, the Zeroes made an improvement. I think that for the majority of loudspeakers, they will not only make that kind of difference, they are required. However, as I noted, there is a significant loss in the OTL magic. My opinion is that if someone were to go down the OTL path, a better option is to choose a high impedence loudspeaker from the get go. That way, none of the life of the OTL amplification is compromised whatsoever.
