I know that Nordost recommends 1.5 m but I haven’t personally heard a difference between 1.5 and 1m. I’m skeptical about these type of things that are not noticeable to your ear. I suppose you could tell a difference if you compare based on measurements alone but not actually hearing a difference. Now, the balanced vs unbalanced issue with analog interconnects and length causing hum is another story.
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?!?
