Thank you for the info. I didn’t think about that when I built my room. I have LED track lights on dimmer switches. Would it present as sounding grainy /static? I figured the recordings that have some grain were from the recording.
Isolated ground in dedicated room/new construction?
Am building a custom house from the ground up with a dedicated listening room. Room will have have 3 dedicated 20 amp home runs for the system using 10 gauge 10/2 romex with ground, terminating with PS audio IG 120v outlets. Romex NM wire with plastic boxes, no metal boxes or conduit. House will have 400 amp service utilizing two 200 amp panels. With this set up is there any point in setting up an isolated ground and how do I go about it? Is it even feasible?
