Looking very nice!! A lot cleaner than your previous place. Better colors & less cluttery.
One thing that would drive me nuts (not being mean!)
What is to the right of the front right RF83? Could you move your sub to the front right corner? If you did then you could center your component cabinet directly under your tv then have your mains equal distance apart. If there is a corner to the right you may get more output out of the sub & have a symetrical setup with your tv, cabinet & mains. Just a thought!
HomeDepot & Lowes have a little section that carries any cable management tracks. If you rent or dont want to open up holes in the wall you can use the track system that sticks to the wall with double sided tape. You push your cables in the sleeve & snap a white cap over it. I used it at my place its very easy & looks clean. I painted the cap the color of my wall & you can barely even see it. It would be perfect for your tv's power cable & HDMI.
Otherwise looking good!!!
Now time to save up for a real sub! Think SVS, HSU, Rythmik!! (sorry had to say it, we were all thinking it).
