Markus1299, assuming you use the same wire to extend the length of your three dedicated lines, after break-in, I dont think you will hear a difference in sound or have any type of voltage drop..
Ckoffend, I dont know what hospital grade cabling consists of that your electrician is recommending. I remember reading years ago that 10 gauge stranded cabling with ground twisted (such as put in drill and twist while elongating) is the way to go. This must then be run in conduit. Its usually easier and costs less to run Romex, and Im not convinced that you will hear a difference in sound.
