The Ait Tight and Atma-Sphere are in a completely different league than the Music Reference IMHO. Never heard of Dodd. Both these companies have long-standing high quality reputations. Ralph Karsten of Atma-Sphere is almost legendary in this regard.
If you do go OTL, you will need to have an appropriate speaker in mind. They don't mate well with everything. But when they do, they are amazing.
I would discount R_f_sales disparaging remark to "check out a real OTL design", which is code for "the Berning isn't a real OTL design". This topic has been discussed at great lengths elsewhere in the archives. The point is that they are both great amps, and if you get a chance to hear the Bernings you will likely hear things that few amps can accomplish. The similarity quality in sound of the Bernings, Atma-Spheres, Joule Electras and other OTLs is something that is rare overall, and difficult to do justice in words. Cheers,
Spencer
