floor speakers upgrade


I'm lookin for an upgrade from my current floor-standing speakers. I've had the Pioneer SP-FS52s for quite a while now and I've recently come into some extra money and hoping I could make an upgrade. I'm not really too knowledgeable when it comes to audio equipment so I figured here would be a great place to start. I've got about $600 to spend but I'd prefer to spend less if at all possible.

Just a quick search on Amazon brings up hundreds of products so I'm unsure of where to start. I found this http://www.pricenfees.com/best-floor-standing-speakers.html and from what I can tell they have some good information. I've got my eye on the Fluance XL7F's which are within my budget and seem to get good reviews in most places. Anyone have experience with these speakers or have a better suggestion? I'm lookin to make a purchase within the next few days.

I appreciate any help you can give.

You really should listen to a speaker first. If not, you can make a big mistake.

If you have no choice, see if you can find a good used pair of Vandersteen Model 1's. Its a very neutral speaker and you can do a lot with it as far as altering the sound to fit your taste. Providing you like the way they sound, it will be a huge upgrade in sound quality for you.
Thats my only issue is I wont be able to have a test-run with the speakers. Most of the electronic stores by me don't have much of a selection unfortunately.
