b) My amp is hooked to a desktop PC. Should I keep the volume level on Windows maxed and just use the amp's knob to adjust the volume? Or always keep it lower than it is on the amp?
1. It depends on your amp. Some amps(many in fact) have protective relay, which protects the headphones. Try listening to your amp as it is starting up. If it pops loudly, I recommend that you plug in your headphones after it is fully started. If the pop is quite(or moderate) or non existent, you can keep your headphones plugged in all time.
2. Yes. Keep your source(your PC in this case) to max all time. But if it starts distorting or cracking, it is ok to turn down the volume on your PC a little. But I recommend keeping it at high levels. This allows less distortion.
Hope this cleared things up. This isn't like a controversy of a myth. It's just science.
