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.

On the USED market if you stick to well known brands and buy at good prices the "try them at home issue" becomes a moot point ... if you do not like what you buy, recycle (resell) and try something else! That is the beauty of AudiogoN, eBay, etc.
If there's a Best Buy with a Magnolia Room near you, go listen to some speakers. You really need to hear the different kinds of speakers rather than reading about them.
Elac F5 tower review by Steve Guttenberg. He even had this to say when he compared them with the OP's Pioneer towers:

When we hooked up our Andrew Jones-designed Pioneer SP-FS52 towers for a head-to-head match, we were taken aback by how different the two towers sounded. The SP-FS52s were softer, warmer and less dynamic and clear overall. The Debut F5 is a major advance over the older design.
