1.0 or 1.5 m digital interconnect, does it matter?

Hi folks, in theory 1.5 m length for S/PDIF should be better than shorter lengths. But in real live does it matter much if the cable length is 1.5 m instead of 1.0 m? I mean, does one hear clear sonic differences between the two lengths? Does one for example hear a grittier sound with the 1.0 m compared to the 1.5 m cable?
