They are are lot cheaper than the list price, since you get the center channel for free with the mains with the current promotion. They are a bit overpriced at the list price (the 95Fs) since it's really mind boggling for $5000 you are getting a 2 1/2 way with aluminum drivers.
Also I don't know how you can say they measure "relatively well" considering that graph basically has a 20db window all squished up.
If you stretch the y axis it looks more like this:
From what I can see the main draw of the Prestige is a compact 3-way center channel that can fit into a typical A/V cabinet and the amazing glossy finishes, followed by QEF styling and very well protected drivers (from kids or pets)--this a speaker you can hang out in all it's glory and not have to hide it behind the grills for protection. Acoustically it might be a bit suspect however, particularly at it's price range. But as a complete family or lifestyle product you have a decent argument for it.
As far as the market, Paradigm Signature speakers hold their value pretty well. But the Prestiege speakers I've seen on 2nd hand sites basically go for fire sale prices, so it seems they aren't considered very highly by audio enthusiasts.
