What people are missing here is the Sophia is a much more forgiving speaker for your upstream gear. Easier to drive and easier to match. Based on looking at your current system I would keep your Transparent Cabling and your ARC CD3 player (skip the Marantz or at least head to head test them).
I'm not sure if the Marantz Integrated will sound as musical as you are use to with the Pathos integrated. You might consider an Accuphase Integrated instead, then it will be more musical and better built. Pretty good combo with the Wilsons.
