Ok I’m a newbie so go easy on me,I have been running rega p3 into the Zp3 to my amp with no hum issues,today I added a ZMC1 to the system with a Hana sl and now I have a noticeable hum,I grounded the sut to the ZP3 and the hum reduced somewhat,then I tried grounding the amp to the SUT and the hum reduced slightly more,any suggestions on how to eliminate the hum altogether,would using a power cord into the sut help ?
I’m not the most tech savvy so simple suggestions would help.Thanks inadvance
