Atmasphere amps trustable?

"Mommywahwah": That type of response to the OP is utterly uncalled for. The OP simply wanted to have a discussion about this brand of OTL and become informed via help and support from our community. If you’re not able to participate in a civil manner and help be supportive, you are antithetical to the existence, and interest, in this hobby/pastime/enjoyment/entertainment endeavor. If you think that’s your charter and mission, then stay away.

Keep your poison and your anger to yourself and get off your high horse. If you have something positive to say, then say it, otherwise keep it to yourself. That’s not why we’re here and not what is helpful and supportive in growing interest in the enjoyment of audio gear and music listening.

B: I hear you, thank you.

When I encountered the OTL concept for the first time and read about Futterman's early efforts along with a few editorial accounts of experiencing "sonic bliss" but with the acknowledgment of some (potentially tube only-based) unreliability issues, I researched more and learned about a design that seems to make sonic sense on paper, and in some critical listening, but has challenges matching optimally to the impedance spectra of many well known and popular speakers. Still, the ability to make it work reliably and sonically is cited to have improved even though the ~4 Ohm output impedance still seems to a limiting factor; it's difficult to apply the ten-to-one minimal nominal speaker to amplifier impedance ratio often cited in order to maintain flat frequency response.  

I would love to hear an OTL based system properly set up. So, perhaps while I don't know what I'm talking about either, I am interested in hearing from those with real experience owning and living with OTL amplifiers. I also agree that to jump to a critical stance without knowing is not the best choice, but I am humbled by the experience and expertise of others to help enlighten. 

Been reading about Transcendent’s products. I want to build one (or two monos)!
