Hi, I decided to move my PS3, it was getting too hot where it was. So In it's original position, about 10cm from the amp I had a short optical cable for the sound (the amp has no HDMI ports) and it was working fine. In it's new position it's around 3m from the amp and I have used a long optical cable but get no sound. I havent changed any setting on ether the PS3 or amp. I'm pretty sure the optical cable is ok, the opposite end shines red with the other end plugged into the PS3. Could the PS3 have a weak optical out, so it's enough for a 1m cable but not 3m. Is it worth getting an opticle cable booster, seen them on amazon, they say they can boost upto 20m, or just getting another cable. Is there any other options, like optical to coaxial? Thanks.
