I am thinking of buying the Denon 500 system but am a bit wary as have looked at the back of it and not sure how I would connect NTL box to Denon to TV?? Will standard scart cable result in best sound and picture??? I have an old box so it has L and R phono outs on the NTL box. So what do u think? Also, as the Denon has its receiver/decoder built into the main unit, will I have to leave it powered on to get sound all the time from NTL or can it be left in standby>??
