Should I pull the trigger?

I have a chance to pick up a nice pair of Triangle Celius 202s, but I already own a set of PSB Stratus Silvers ('i' version). To me, the Triangles appear to be similar to the PSBs in physical size and driver complement (although the Triangles may sound a little more refined?). The current owner of the Triangles is using them with a tube amp, which tells me they've had an easy life and probably have not been abused sonically. I really like my Stratus Silvers and have owned them for about 10 years......they do so many things right and so few wrong in my book. I've always wanted a pair of Triangle speakers and don't want to miss this opportunity, but have misgivings that I'd just be buying another set of Silver i's, so to speak. If I get the Triangles, I plan on using them with a Thule Spirit IA-60 integrated amp.
