What is the best OTL out there?

Hi 
analoluvr  admittedly with all things considered I do generally prefer tube  amplification rather than  solid state.   In all candor however I have heard very good sounding solid-state products so I won't throw them all out with the bathwater 😊.   Good  implementation of tubes sounds more natural to me  more often than not. Just a personal observation over the years.  I do acknowledge that solid-state dominates the audio market.

 Yes I have heard some very good solid state as well. However I took atmospheres comments to apply to solid state as well but I could be wrong about that as I don't have much knowledge about solid-state here. I run a pair of atmosphere M60s and I am a big fan though admittedly have not heard any other OTL. I did have some pretty good single ended triode amps and preferred the 0TL to that. 

OTL owners always say's the best what they have without comparing other OTL.

Hello Analogluvr,
I’ve heard the Atma-sphere M 60 and also the MA-1 mono blocks and can appreciate your happiness. I’ve had the Coincident Frankenstein MK II SET for 9 years and remain an ecstatic owner. It’s terrific to find audio products that truly satisfy.

@realdeal,

OTL owners always say that the brand they own is best even though they haven't heard any other brands (not quoting you verbatim here since your choice of wording was so vague/unfortunate). I would say that your observation is largely correct, just as it would be for the SET crowd, the push/pull pentode contingency, the solid state class A fanboys, etc., etc. 

Bottom line, this approach is endemic to virtually all audio discussions concerning any audio gear genre you wish to become involved with. Get used to it.
