No mate, and one piece of advice is even when you have chosen your system, go over it again as well as what you want it to do before you pick out everything and put it in.
You have a great advantage and that is time, you can dream about it a little lol... not to much.
make sure you run ample cables, I cannot stress this enough, if you want 3 cat6 then run 4/5, if you want 1 coax, run 2.
Do not forget to run the subwoofer (RCA) cable to where it has to go, do not school boy error this and run speaker cable, run a cat6 with it too as if that cable fails you can balun phono with 1 cat6 easy
and very CHEAP too lol.
I do bang on about running extra cables, and that is because I have seen it so many times, EVEN this week with one client that SAID and stressed she would only have freeview in the living room!!! I told her 2 coax she said one, it saved her 70 pounds at the time, now its costing her 300
... now she wants to put a sky box in a cupboard and we have to run a cable outside the building... see what i mean lol. Also future proofing is important, how does anyone know what the next person that lives in the house wants.
