Hi guys and girls, BLUF: Thinking about building a dedicated headphone amp to sit beside my computer. Curious, what would you look for in a dedicated amplifier? Details: Recently, I've been talking with a few of you and reading the thread about op amps, etc. There seems to be a lot of interest in modding/swapping parts and general customization. That's so inspiring! Since we like to build our own systems, I thought why not build our own headphone amp to set beside them. The idea is a simple, analog amp that anyone can build. In the style of "Lego" building guides, there will be colorful 3D pictures of parts being assembled, schematics, and explanations of what each section of the circuit actually does using understandable language. Thoughts?
