coaxial digital cable lengths

at the moment i have a 1m length of kimber dv-75. I am looking to upgrade to the top of the line d60 cable. Only prob is that i can only get it in .5m length. the guy who i purchased the 1m off said that ide be better off sticking with 1m length because if i go with anything less i will likely end up having audio dropouts and problems like that. I find that a little hard to believe.
Anyone know if i would be totaly fine going with the .5m and there will be no difference,(maybe even a slight improvment over the 1m?) or will i end up having issues with it?
thanx:confused5:

There's no reason you can't use a .5m length. I use them and never have any problems with dropout.

On the other hand, there's no reason to upgrade either.

You will be fine with what every length you use. That guy does not know what he is talking about.
