Hi guys, I have a noob question. I use my PC to play music. I have a PC connected to a DAC Topping D10S. Then I have this Topping D10S connected via SPDIF to a DAC Topping E30, which I have connected to my speakers. I was having trouble with the ground loop, and of course that SPDIF between the Topping D10S and the Topping E30 solved it and the sound is fine. But I also have that Topping D10S connected to the Topping L30 headphone amp, via RCA. And I switch between them. When I want to listen in the headphones, I turn off the E30, turn off the speakers and turn on the L30 AMP and listen in the headphones. But I wonder what would happen if I had the E30 with speakers on and the L30 with headphones on at the same time. Wouldn't that damage the hardware somehow? I haven't tried it yet.
