Yup off the floor makes it a lot easier to clean under. Remember the magic happen on the outside of the wire not the inside. The fields expands and contract. Do they sound better laying on the ground with static discharge and dust bunnies or off the ground with a narrow insulated lifter and vibration control? Cable routing is an art, it's just as important as the cable construct it's self..
BUT if your a hook, drop and let er flop, kind of person, I'd stick with XLR and watch the routing just to STAY out of trouble, instead of getting out of trouble..
