The heel of the 001 is that the power lines are right beside the digital lines, so the longer the cable the dirtier the power supply is, but really the damage is already done inside the computer itself, just like with any bus-powered interface. Either the power supply from the computer is reconditioned in the interface with a switching power supply (ie RME interfaces) or it isn't. If memory serves, the 001 only has passive noise filters. So the short version of all that is that the longer cable doesn't help, but go ahead.
