To answer your question - yes you will hear a significant improvement in the music your system plays when you upgrade the wall outlet. It is simply that simple. Since this will be your first experience with this part of the audio reproduction chain, buy an outlet that you can return if you do not think the change is significant, or watch the used listings here at Audiogon and buy a used outlet that you can resell if you choose to do so.
Elizabeth has done a lot of critical listening with the Furutch outlets and I have done the same with Furutech and Synergistic Research outlets. These outlets impart a significant improvement to a system.
I do hope you you will give audio grade outlets a try.
