I have a Fiio A3 Headphone Amp that I bought about 3.5 years ago and rarely used when I realized the problem was probably more my phone and headphones than anything else. It could probably be used as a pre-amp between your computer and a pair of active speakers. I have no need for it and would like to find it a home.
