yep, you need to figure out which ones sound better to you, i have heard some very expensive speakers that i just did not care for including some speakers that were around 7k-10k a pair, most of them sounded great but they did not quite have that sound that i like to hear. some sounded to dark, some sounded to bright and some just plain sounded bad to my ear. for instance the couple of sets of Jamo speakers that i have heard sounded horrible to me, it could have been the room and speaker placement that made them sound bad for all i know which is another issue. so i always make sure i can return the speakers if i take them home and they do not sound like they did in the store.
some people will buy both pairs and return the ones they do not like as much, not sure if you can do that or not, if the place has a good return policy and you can afford to buy both, or put both or one or the other on credit. that way you know you will be happy and get the set of speakers that will suit you best.. and you want be setting around wondering if you should have got the other pair
its really all about what you like. when i audition speakers i like to take a CD with different types of music that i like and see how it sounds for rock, country, blues, bluegrass and so on. one thing i have noticed is quite a few sets of speakers sound very good for everything but rock and roll music. when it comes to the distorted guitar on rock music, i want to hear a nice warm and smooth yet driving guitar sound, and i make sure i have a few rock and roll tracks where the guitar is recorded with a warmer sound and some where the guitar is recorded with a bright sound
