Nikki, use Google to search for reviews about the gear you are interested in buying. Just type in the equipment name, model designation and the word "review" and you will probably bring up all kinds of hits.
I did a quick search using "Athena speaker review" and lots of stuff came up, but it is better to be as specific as possible regarding the models you are searching for.
When I was looking for a replacement receiver a year ago Google was invaluable for finding reviews and user boards about various models. I wound up buying an Outlaw Audio 1050 receiver and I could not be happier with my purchase...
