I have the following - Pioneer 435xde, Denon 3805 and DVD3910. Currently thinking of KEF KHT 5005 speakers. Have purchased the Chord Supra Silver HDMI cable but was interested what other connections people have used for their Denons? I use my system 99% of the time purely for films and DVDs. Anyone recommend optical connector, speaker wire and sub connector. Any advice would be gratefully received.
