Hi Wattbel,
For $1500 you can get a very nice setup. I will try to talk you out of wireless speakers - they tend to be more trouble than they are worth. There are many ways to hide the speaker cable to the surrounds (BTW - 5.1 setups, the "rears" are not really behind you - they are to either side of your main listening area).
For your budget this is what I would get:
Onkyo 607 - about $450
SVS - SBS-01 - about $950
cables/wires from Monoprice.com or Blue Jeans cables - about $30

Check back often - I'm sure you will get more recommendations....
BTW - It is always best for you to go listen to speakers yourself. We all have different tastes.
