rocray, sorry, I thought I answered that question. Only one dot per interconnect, so 2 of them for a pair of interconnects. I have them placed at the source end. And in my case since I am running direct from Lumin X1 to my mono amps that is all I need.
At the speaker end, I have one per speaker cable so 2 more. So, a total of 4.
If you have more interconnects you can experience, I guess, by adding additional dots to each of them at the output point.
