The only reason interconnect that short could harm sound is if it caused stress or loading (feedback) between two components that should not be mechanically connected.
Perfect example is turntable to phono stage or phono stage to preamp. This is not always an issue, depends on design of equipment, if tube or transistor and lots of other things.
Many cables have a minimum charge that covers up to 1 meter. Buying .5 meter may save ZERO money and harm resale if you should decide later to sell to upgrade.
Too, most cables have a basic charge and the .5 meter increments are a tiny fraction of the cost, meaning little money is saved, even if there is a discount for the shorter length.
An example is the Purist Museaus, 1 meter is $300.00. .5 meter is $260.00 (these are retail prices but you get the idea).
