I would thoroughly recommend LessLoss cables (interconnects and power cables)
Their C-MARC range has some perfectly sensible science behind it (as per humbucker coils for the guitarists amongst you), explained in depth on the website and my experience has been that they made a spectacular difference, presumably by cancelling/rejecting RFI/EMI
I am slowly working my way to a full loom
For example I have an industrial balanced mains transformer that used to hum whenever the missus used her hair straighteners upstairs. Once I added a LessLoss mains cable, the hum totally vanished
They're not super cheap, but neither are they crazy expensive (give or take $800 for a pair of ICs)
