As one newbie to another I think I can pass on some advice I have gleaned from this board.
Bonthouse mentioned two very popular plugs and I would like to add the 3.5mm and 6.3mm plugs from Neutrik.
Regarding cables, there are several distinct options as I see it. The first is to buy silver plated copper wire (ebay is a popular seller) and to braid for lengths together. Another option is to buy a quad cable buy Canare or Mogami and split the cable at some point so that you have two conductors going to each side. This route is "arguably" the cheapest and is very popular, however, I am afraid that, in stripping the pvc jacket and stripping the cable, I will nick something and destroy a perfectly good length of cable. I will probably go the star quad route because the jacket, insulation and fillers used in star quad cables make the cable thicker, stronger and allow it to flex.
