Well if both offer a 30 day return, you could bring both home and return the one you don't like.

The way you have to do it is better than nothing but you will be listening to 2 different speakers, in 2 different rooms and most likely different electronics, I'd suggest at least bringing your own music. I like listening for detail, and balance, is it overly bright or bass heavy etc. But I think you will know if you hear a speaker you like, or which you enjoy the most. Keep in mind you are the one who sits and listens to them, so you are the one you have to please, so don't let some one try to talk you in to something, trust your own ears.
