Please evaluate my system...

Your components look very good.
Are you using dedicated circuits for your system?
I start with the AC power and power filtration system including outlets before I move up to the component line.

@tim_field, Regardless of any type of power conditioner used dedicated 20 amp circuits runs with 12 or 10 gauge wire depending upon the distance and ones personal preferences is a must in my mind if its a possibility within your home. That one change will improve the sound of your music. Good AC quality outlets are also important.
I totally understand that the origional question you asked was centered upon compoient upgrades however the foundation of any construction site is extreamly important.
