0.5M of analog interconnect would in no way "hinder" the sound at all verses the 1.0 or 1.5M lengths.
You may save a bit of money with that length over the 1.0/1.5M sizes, but it may effect your resale of the cable as it limits placement and component configuration. Many like the flexibility of the 1M length..just a thought.
Only digital cable such as 75ohm S/PDIF coax type or toslink is recommended to use as a standard 0.75M length connect( speed/velocity propagation theory)
