Ok, I've assembled my Opus and my pair of Ventuses (Venti? Ventae?). I had a problem with noise on one Ventus board that turned out to be due to a dodgy solder joint on one of the power supply caps, but that appears to be resolved.

So I hooked up the Opus to the inputs and set about removing the DC offset. I've noticed that the voltage present changes with time so I left it for a while to warm up and then adjusted the offset out. However, after leaving it for a while longer, I've noticed that some voltage returns, generally somewhere between -1mV and 1mV.

Is this normal? Or is this indicative of some issue in my build?

1mv offset is generally nothing to worry about. If you really need something lower than that you might just need an AC coupling cap.
