Hey RickyDeg,
Definetly we can compare our findings. I will look out for a 4520 to demo once they're released. I want to see how different it sounds to my A100 (if it does).
You took the words right out of my mouth about the additional AW12 and the Front heights, I've been thinking of getting two additional A10s for Front Heights and using the Audyssey DSX mode. I had a read through some forums on DSX and some people were not too keen on the setup saying that it doesnt offer any advantage to a 5.1. So any advice or sources you have will be helpful. I'm defo on the additional AW12, i think it will make a difference to my setup.
I will upload pics of my system soon, i never seem to have the time during the working week but will try over the weekend.
Cheers
