This has been in the works a while. At the request of friends (and a few critics) I've designed my own portable/desktop amp: The Objective2 (O2 for short).
It's a very objective approach (what would you expect from an electrical engineer?) at a low cost "one size fits all" headphone amp. The goal was to show how much performance is possible on a limited budget. It's designed to outperform even far more expensive desktop amps using solid engineering rather than audiophile designer parts or mythical circuit designs. To put this amp in perspective it will overall outperform everything FiiO makes including the E9 and E11. For now it's a DIY amp but it's a free open source design and a few commercial companies have already expressed an interest in offering it as a kit, pre-assembled circuit board (no soldering required) and possibly even as a complete amp. Some have called it the spiritual successor to the Cmoy but the performance is an entirely different league (sorry for not being more modest!). Some highlights:

It's open source hardware licensed under a Creative Commons License. For the DIY crowd, once I have the final article online, I'll be starting a thread on diyAudio for those interested in building one. For everyone else, if the O2 is popular, there should be some options in the next few months to purchase it without any soldering or special skills required. I know many are probably curious about the price, that will be in next article. But as a hint, it was designed to outperform its closest current competitor, the AMB Mini3, in every way including the price. ![]()
