Dedicated 20 amp/ground loop question

Hi all.....I am getting ready to start construction on a new home and I am trying to get all the plans ready for the electrician for a dedicated 2 channel music/library. I am planning on having the speakers on the end of the room (18 X 23) and a McIntosh MC352 amplifier placed in between the speakers on a stand. I would like the rest of the equipment on one of the side walls so I can run 1 set of balanced ICs to the front and that's it.

I am planning on having the electrician do the dedicated circuit(s) to this room....I've read on here about the existence of ground loops if you run 2 or more dedicated lines. I was plannning on having one dedicated line to the digital/preamp/etc. on the side wall, and one dedicated line to the McIntosh amplifier. Does anyone know if this arrangement would have a good chance of producing a ground loop since the receptacles will be separated from each other in the room?
