I purchased the USB and RCA cables from monoprice
I was going to mention monoprice, but since I haven't used any of there cables for my Magni/Modi I didn't mention it. I have had great experiences with their cables and adapters on my other gear though.
Amazon cable with my Modi and have no problems what-so-ever and it matches my desktop lighting.
Then I use the PYST interconnects from Schiit.
