In Reply to: You would still have a ground loop. posted by Al Sekela on July 3, 2007 at 15:13:22:
assuming the amp is grounded as you described, if the source's audio zero reference is not terminated to safety-earth ground point on the source's chassis (all wood), but the source component nevertheless has a 3-prong IEC with ground blade referenced to safety earth bolt in chassis to which only ground wires from EI transformers are terminated...would the potential still exist for ground loop?
In this example, the source is a dac housed in wood chassis connected to upstream transport that has audio zero reference tied to safety earth ground.
