I suspect you have the old version 1.0 or 1.1 pcb, with the old 1.2 firmware.Hi, need some help. recently got the su-8 and noticed a weird behaviour.
If i'm on balanced cable connected to my amp and i switched the input from usb to optical while music is playing on the current input, there will be an extremely loud boom and subsequently no sound is coming out.
This does not happen if i connect the su-8 via unbalance cables. Has anyone else experienced this?
The popping sound you hear it's a problem they've fixed in the current revision units.
If you've got the old unit I suggest you to return it and make sure you get the last version.
