Static issues almost certainly have nothing to do with the cables. Rather, there is no "preference" for the Magni in regards to the types of cable. I personally use the LC-1 RCA interconnect from Blue Jeans Cable (one foot works fine). Like the PYST cables, I have to have a zip tie around them, but they're super high quality and not overpriced.
Definitely have to disagree. It's not so much just static but lots of noise with poorly shielded cables.
As long as you have good shielding you have nothing to worry about. Most cables won't be a problem at least.
Some cables have awful shielding. The Guitar Center Livewire cheap cables and the Monoprice thin ones are awful.
The RCA/GE ones at any Wal-Mart are surprisingly good.
If you get Monoprice cables, get the thicker ones which are like 98% plastic.
Also..there can be different types of static/hissing and popping sounds. If you get screeching/hissing/static/popping/cut-outs from your DAC it's due to a crappy USB port. When I used my HRT MSII I often got sound popping and screeching when connected straight to my laptops USB ports. I don't think it's due to a lack of power but just a horrible USB port. Sometimes switching ports works, but not always.
I can't use my ODAC or my old HRT MSII without a powered USB hub. I will never use a USB cable with a ferrite bead. I really think my laptop's USB ports are garbage. Even the ones on my custom built computer are awful.
I do however use a Ferrite on my Magni..not sure if this helps, but can't hurt.
Oh and I wonder if the Modi already has a ferrite bead inside?
