    PIMETA v2 IC2 short

    I got to the step in the build where you test the voltages before you put in the DIP8s. The problem is, IC2 , the “rail splitter”, started sparking a little. Do you think it's salvagable at all?

    Disadvantages of using optical out from PC to DAC + Amp?

    Hi,   I normally only listen using headphones at work where I am running a USB DAC (Music Streamer II) connected to a PPA. At home, I just use cheap 2.0 speakers with a line out from my motherboard. I noticed my motherboard also has optical out and possibly digital coax out as well. I have a...
