You might want to post this question at DIYaudio.com. Also, I recommend building two separate ground boxes - one for analog, one for digital. Surprisingly, I discovered that even the ground wires can pass along digital nasties to analog. When I re-routed them separately, the SQ cleaned up.
Need Help With Building DIY Grounding Cable
Hello,
I am planning to build a DIY grounding box. I am planning to connect my DAC and Integrated amp to this grounding box by connectig the unused RCA input terminals on the both. For this I need to create two cables with Banana at one end and RCA at the other end so that I can connect them via speaker binding post on grounding box.
I need help with how & where to attach (solder) the cable on RCA socket.
I also need help in understanding if I can connect both L & R RCA input sockets on same amp to same grounding box (assuming I am going to solder the wire on the shell/-ve part of RCA connector)? Also Can I similarly connect all unused inputs on DAC/Amp to grounding box.
I understand attaching multiple inputs to grounding box is not going to amplify the effect & I just want to do it for protection of those input terminals.
Regards,
