I'm soon to take delivery of a DV79 & a AV300, which I intend to connect to a Sky HD box & a Plasma TV. As this is a system upgrade the speaker cables are fine I also have a coaxical cable running between my current amp & dvd so ok there " I hope". I've also got a descent HDMI lead to run between the TV & DVD, will use the Sky supplied one for the HD for a while . Also I believe I will need an optical cable between the amp & HD box. Is there anything I've missed?
