Hey all,
I got my computer about a month ago and when I first plugged in my computer and the Topping TP60 into the same power bar, I heard a loud whine from my HE-500s and I was really confused about the problem so for about a week I didn't use the amp. For the time being I used my E17 as the DAC and Amp and then I got the idea that I would use a power outlet from a nearby room for the Amp and that fixed the problem. However 2 weeks later we moved and the same problem persisted but this time, using another outlet in an adjacent room didn't fix the problem so I am stuck here using my E17 again.
I did some research and found that it probably is a ground loop issue but I am not completely sure. I was thinking if using an RCA ground loop isolator would fix the problem since unplugging the RCA while the amp was on and connected to the HE-500s caused no sound interference. Also to note that when I was getting the interference, I could hear my clicks in the interference so it could be I need a USB isolator. Another interesting thing is that when I used my phone as a source, there was no loud whine. I am not sure what the problem is and would really like listening to the HE-500s with the speaker amp.
I was thinking something like this might fix the issue.
