Lifting the ground is always dangerous and I can't believe MiniDSP would recommend that. While I am sure not to "code" you can mitigate most if not all of the "danger" of lifting the ground by using a GFCI outlet.Well that's strange. miniDSP support told me it's completely safe to lift the ground of my speakers (Neumann KH120A). Gotta find out myself if I get a Pikachu?
