Assuming you've determined a good listening triangle, do nothing else and just listen to your music collection. Familiarize yourself with how your music collection sounds on your new components. Take your time in doing this. It's only after you really know what your system sounds like can you figure out what you need to do next.
BTW, I would address room acoustics first. Keep it minimal.
