[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.

Every so often, I like to check out the headphone amp scene at [headwize]. The headphone lovers there never seem to stop. This little amp is one of the latest creations. The latest is the mini v3 – it reflects a trend I’ve been seeing on homebrew hardware: SMD core chips and through hole components for support hardware. A 9 volt supplies power, and a pair of linear regulators. It’s a nice simple, solid design – and you’ve gotta love the thumb screws. (I’m not sure how a more efficient PWM regulated power source would affect the audio output)
