Hi all, Been running my denon 550sd for a few weeks now, and very impressed! Now I have been paid again, I can afford to upgrade my connections. Please can anyone recommend the best cables for these below? Optical cable for DVD to AV surround amp - max £30? Optical cable for digibox to AV surround amp - max £30? RGB scart from digibox to TV - max £40? Component cable from DVD to TV - max £50? Really appreciate the help, thank you. Sam.
