    The CMoy++ ==With 3D printed case==

    I finally got all the parts I wanted for the base model of my CMoy++ so I started to prototype it out on a board from RadioShack. (I'll borrow a friends camera to show how it looks later) It's basically a CMoy with a real ground, buffered outputs, bass boost, and a DC jack for charging the...

I tried both and found that the 4556 worked much better for my purposes (low impedance headphones with a bass boost circuit implemented) the only issue was, with the bass boost...

    I built a CMoy because I am noobish. One channel has 36mv of DC offset and the other has 8mv. True the Opamp in it is about 5000 levels below sub par (have a nice BB coming in the mail soon) but I'd like to know if there is anything other than the amp that could be at fault here (the amp is a...
