And not just tested by the designer, but by others potentially with a bone to pick. These others haven't found results that disagree with what's out there. Also Tyll at IF to some degree. So it is better-known, for whatever that is worth. You can check the schematic too.
Schiit allegedly and most probably does plenty of testing internally (all the right ones? maybe, maybe not); they just don't think it's important or a good idea to publish all kinds of results. Most importantly, like many other audio designers—correctly or not—they probably don't believe the measurements they take are enough to represent the sound of the products. Part of their marketing is how they're not numbers guys pursuing the top benchmarks. Also, not that many people are interested in see all the measurements. Many companies post even fewer specs. Furthermore, any specs they do publish may likely be misunderstood by a lot of people (particularly at the point where numbers become good enough, further improvements don't really mean anything). Finally, of course, the specs would be worse than some others. The last thing a manufacturer of vacuum tube amps and champion of minimal feedback wants to do is get in a numbers war. It tends to be gear intended for the professional market that comes with more published testing results. And those with the best results, of course.
Personally I'd like to have more information available about everything, but I don't think they're all out there to cater to me.

schiit seems to be more secretive in keeping their designs known, patent issues maybe, with the praise that O2/ODAC is being given as a good design, its like you're all discrediting schiit's engineers, whom I think are quite brilliant themselves,
ODAC is not open source, cannot be DIY. (party line is that chips used require NDAs and so on, which is true; some people furthermore suspect ulterior motives, money under the table, which you may or may not believe). O2 is.
It's not at all a fair comparison from the designers' point of view in terms of information available and transparency because Schiit needs to make money and stuff, keep things under wraps. No company wants to disclose too much to the customers and competitors. From the consumer's point of view, depends on your priorities.
I think one of the most interesting differences here is that the O2/ODAC designer likes (sensitive, relatively high-end) IEMs, and of course some others. If I understand correctly, Schiit owns or listens to or uses some planar magnetics like LCD-2 or something. I forget. Probably others too.
So the O2 gets extremely low noise. Magni gets high default gain and lots of power at low impedance loads.
