The Cambridge is still my favorite budget friendly speakers, and they are a little beast.

And, I prefer them over the PSB Image series. > Also, I would prefer the bookshlf (1 ea)
for the center, over their center channel.
I have not listened to HSU - so I can not speculate about their quality - however, they can
be a nice option for you.
My first recommendation would cost you $1050 for the front 3.
The second, about about $850 for the front 3.
Enjoy the search adventure!
