My buddy gets out of one issue and falls right into another. This is on a second system he has setup.
B&O TT into Project pre into Outlaw receiver - all good.
B&O TT into Schiit pre into Outlaw receiver - POP sound when stylus touches down AND when it lifts off.
My 1st thoughts are the gain of the pre is too high or the pre has a faulty ground. Told him to look over the gain settings, try them all. If that doesn't resolve it, remove the ground cable and see what happens.
Any other ideas?
