I used the Belden 1505a RG 59 cable, and Canare RCAs and BNC connectors. I think the Belden 1506a (which uses Teflon insulation) might be better, but I never tried it. I bought everything (wire sold by the foot, and connectors sold in singles) here in the U.S. through an outfit called Markertek. They had good prices (less than $.60 foot for the wire, and the connectors were under $3.00 USD each), provided fast service and delivery, etc.
Certainly very reasonable to try, and I think you'll be impressed with the sound.
