Recently upgraded with a new set of speakers, this is my hifi system in my living room. The room is far from perfect, but it's not terrible either. Been dialing in the speaker position recently.
If this was my system I would start upgrading the power cords. You will be surprised at the characteristics that your system has that you are not even hearing! I've been experimenting and upgrading cables and power cords for several years and when you get to the upper levels of the Shunyatas, Acoustic Zen, JPS Labs, Harmonic Technologies, Synergistic Reseach etc.. etc.. you will be amazed at the improvements.
