Longer is better for SPDIF cables! Signal reflections in shorter cables can interfere at a DAC’s input receiver. I bought a 1 meter and a 1.5 meter SPDIF cable. I am using the 1.5 meter into a DAC. You can try your 1 meter. It may work fine! Companies should just make 1.5 meter and longer SPDIF cables. They are catering to the audiophile belief that 'shorter is better'. The metal type (copper or silver) doesn’t matter. As the French chef says " No diffawrance!"
Length of SPDIF cable
I've just ordered a Xangsane pure silver SPDIF coax cable and it's already on the way. I've ordered a 1m cable because I've read that "you should not have a too short SPDIf cable". My previous ones were all 0,5m.
But now I read that the ideal length would be 1,5m which kinda makes me wonder if 1m is not just the "wrong" length.
Well I will listen to it, I suppose if it sounds good it's good, but still, why don't they only make 1,5m coax cables if that is the recommended length?!?
