I also agree that Bose isn't terrible but it is priced in an range that gives you many different options. Producing sound is all about moving air and frankly little speakers move a lot less of it. When I listen to a Bose system I hear bright shiny "highs" and deep, somewhat mushy "lows." The smaller Bose systems lack a lot of mid range and the Acoustimass modules are rumbly and soft compared to hard hitting sub with a stout amp. They're are at least 20 different very popular makes out there and it would be worth listening to as many high end systems as you can before making a final decision.
I've been a long time subscriber the Home Theater magazine and it might be worth stopping by a Walmart to pick up a copy. If for no other reason it will be eye opening to realize how many high end audio makes are out there while getting opinions from some people who do reviews day in and day out. It might even steer you to one of the specialty stores for a listen. Generally, Bose is considered the starting point for a home theater / surround system.
Regarding the other makes, here is no "best" in the upper end and it really comes down to your prefference. Mirage, Monitor, Klipsch, B&W, Sunfire, Paradigm, Boston Acoustics, Definitive Technology, Polk Audio, Atlantic Technology, and some of the pro series JBL are just a few to consider. All of it is finer equipment than Bose. Like has been pointed out already, the speakers are just one small aspect of the entire system. The $1500 budget may limit you to a Bose system in the end though.
