Top class Home cinema system

Hi guys,
I have a GigaWorks S750 7.1 system, but the amplifier got broken and cannot fix it. As some of you have vast experience with audio systems - can you suggest the top brands - I was looking at Klipsch Palladium. I will appriciete some comments what is the best you can get :)
Datasat RS20i Pre/Pro
BAT VK6200 amplifier
Aerial Acoustics LR5 speakers x 5
Dual JL Audio F113 subwoofers

These are a sample of some of the best you could get for home cinema....
Thnaks, I will look into it :)
