I also suggest taking the time to address the acoustics first. A move is a great time to do that, because there isn't anything there yet to get in the way. You can also run additional power to the room while it is convenient.
Planar magnetic and electrostatic speakers are definitely options given you have the ability to place them away from the walls. But you should also keep in mind your listening spot, to make sure you don't end up with a setup that you will need to be pushed too hard in order to reach the volumes you want at your seat.
