staples dont short cables....... installers with staplers do!!!
there is nothing wrong with staples. romex staples are fine for speaker wire and coax so long as you dont drive them in to the point where the cable is pinched. dont drive it in all the way you should be able to slide it under the staple to allow for expansion in the wood. for cat 5 and line level i prefer arrow t37 with 9/16" staples or t 59 for a single cable. The t 59 is foolproof as it is an insulated staple and wont damage your cables. give this to the rookies over the t37. But any time you have multiple cables tie wrap you stuff to a romex staple or strip some cat 5 ant use it like garbage bag ties. save your t25 for crafts.
