I noticed there was a small static discharge in form of a small spark when I touched the outer cabinet of my Directstream DAC the other day. The DAC was turned on, but not the power amplifier it is connected to.
Can such a static discharge do any harm to the electronic components on the inside, resulting in any kind of sonic degration? The DAC is performing perfectly normal, but I just wondered anyway. All my equipment is connected to a powerplant P10 with AC12 power cables, but the P10 is not connected to ground.
