Tiny Inline Headphone Amp

August 20, 2007 by Will O'Brien 5 Comments


[Jesse] sent in this headphone amp. It’s really just a board with a dedicated smd headphone amp chip(MAX9725) and a pair of smd caps recycled from an old hard drive, but it does job. I think the goal is to boost low signals rather than the usual audiophile quest for cleaner tunes.
