Somewhat unrelated question: Can other amp designs implement feed-forward into designs to improve their output? I wouldn't think that something like that could really be patented. I'm thinking that an amp that is already nearly as quiet as THX AAA could implement feed-forward, and see improvements. Something based on say, an OPA1622 from TI, or a product like the Atom from JDS.
So far no one really knows exactly how the THX AAA pulls it off. According to them, they have a distortion rejecting mechanism that allows them to use whatever most powerful amp chips without any penalty, supposedly there's no sense to use something traditional like OPA1622 with it.
Perhaps it will be reverse engineered some day but for the moment it seems rather proprietary. The hardware teardown of the THX AAA reveals nothing out of the ordinary, their tech seems well hidden https://www.audiosciencereview.com/...n-of-massdrop-thx-aaa-789-headphone-amp.5327/
