Hi all - Ive done a bit of homework using the site and have to say the content is great but perhaps a little overwhelming to someone as unknowledgable as myself!! I was wondering if someone could asnswer a few questions to make sure I get the best out of my set up? I have a Samsung HD tv, Standard Sky box, Yamaha DSP-A1 amp, Samsung BluR player, Roth Floorstanders, Kef egg rears and a Mission centre speaker.....Im using an optical cable from sky to the amp, HDMI from BR player to TV (picture), optical from BR player to amp (sound). I presume these are the best options but wondered what was best for signal from Sky to TV? Ive tried S-vid to S-vid but there seems to be signal interference? I then tried scart to component (3 phono) and that seems to work without interference. With regards speaker cable....I aim to get QED micro for the rears. For the 2 floorstanders and centre im totally unsure as I was weighing up either 2nd hand cable against new? Any thoughts that can help?!!?!!
