Hi Nisbeth!Most of my raw cables are from Take Five audio, though I have also purchased from Dedicated. Flex and heatshrink from Cable Organizer, and bullet plugs from a friend in the USA. The black RCAs are made by Dayton and are from Parts Express. I wholeheartedly recommend all suppliers, especially Take Five, who really go the extra mile to help.
If you need any supplies, let me know offline!
