    Harmonic distortion phase and it's effects

    For a given output voltage, let's say a DAC outputs a 2nd order harmonic -60 dB down from the fundamental. If that DAC is connected to an amplifier that also has 2nd order harmonic distortion at -60 dB, what is the result? I'm guessing that if the 2nd order harmonic is of the same phase, the...

    Cheap way to increase gain for a line level signal?

    I have a budget system with a receiver, two mains, and a subwoofer connected to the sub out on the receiver. The subwoofer's volume is too low, even with it's own gain maxed. The subwoofer can play plenty loud if I increase the overall system volume, but the relative volume is too low. What's a...
