After some research about headphone amps, a little cleaning of the bookmark collection resulted in this META. Enjoy  :thumb:  and contribute :!:  :!:  If you think that certain links should be removed or moved to a different (sub-)category, please PM/email me or post here, i have not read all threads carefully.


META - headphone amplification (and everything else regarding headphones)

This is a meta-thread, made to allow you to keep track of the posts concerning this single issue. All should be contained in this first post - which is re-edited regularily. Everyone is welcome to reply with comments and pointers to things they consider relevant. This will be copy/pasted into the first post, if the meta-keeper finds it relevant. (We deeply dislike censorship, but here it seems necessary for the sake of overview). On a regular basis, a moderator will delete all posts but this first one, and bump the thread to the top.
