Are you thinking about replacing the EP125's internal amp with this amplifier?
No. I want to connect the subwoofer (using its internal amp) to the system using the speaker-level subwoofer inputs (binding posts). The negative speaker terminals on my amplifier are not at ground potential as the amplifier has a balanced differential output stage.
Thus I need to ensure that the subwoofer doesn't internally connect the left (-) and right (-) speaker-level input posts to each other. I could do this with an ohmmeter but want to verify that it is OK before buying the subwoofer.
