Not a fan of Infinity stuff myself, obviously I've not heard the system but small speakers in a large space with plenty of reflective hard surfaces usually means less than perfect results.
It does look nice if it's going to be a living area but its far from being an ideal home cinema.
It depends how much you want to compromise your home for your hobby and it's a personal choice. :)

I have always found that when you get the tv at home and set the picture up with a good aerial and away from rf interference in the shop, that the picture is vastly improved on what you see in the shop.

I think you will be very happy with that Corrodadoboy.
