First off I would like to thank everyone for helping me make the step to high end audio. There are way more products and schools of thought out there than I have ever imagined and this site has really helped me sort things out. On to the question.....

I have been checking out floorstanders in the under $1000 range and have just begun to listen to a few brands, specifically the B&W 603's and Paradigm Studio 60 (v2). I will be visiting my friend in Philly and will demo KEF's, Energys, and Bostons as the selection in Central PA is rather limited. In regards to my previous post, I will most likely stick to floorstanders. Anyway, a pair of PSB Stratus Silvers and Stratus Bronzes are up for sale on audiogon and right now they are going for $600 and $350, respectively. Both are floor models.

First off, will these speakers hands down beat anything I listen to in the under $1000 range? Second, what is the difference between the Silvers and Bronzes, and what difference will I really hear? Finally, how will these speakers perform with my NAD amp/preamp? This seems to be a good offer, and it's hard to pass up $1600 speakers for such a low price. Tempting indeed! I know I will not get a chance to listen to PSB's before I buy, and I really like getting the opportunity to aduition before I purchase. However, I really don't want to kick myself later for passing up such a (potentially) good deal.
