Just built my first CMOY headphone amp. Had a few hiccups but got through them and now it sounds brilliant! My HD 580s are 300 ohms so they needed some more power, and now they really shine!
My cmoy is not portable, it's powered through a 12.8V wallwart supply...and I changed the power caps to Sanyo WG 1500uF which seemed to tighten up the bass at high volumes. Currently using an OPA2132PA opamp, going to try an OPA2142 in a bit and maybe a few others. I was expecting some background noise because it's running from the line-out on my onboard P5Q deluxe sound but there really is none at all!
My next project is getting a DIY DAC up and running, then I'll be building a Millet Starving Student hybrid tube amp
Quite pleased for my very first DIY project I did mess up on the LED hole though, made it too big. I might look for a larger LED to fill the hole up some more.
