Would I benefit from biamping?

I know that this may fall into opinion, but? Would I benefit from purchasing a second Krell KSA-250a and run them in a bridged mode to my Dynaudio Contour 1.3SE's? Or am I already fine with the power that I have? Would biamping give me that, more immediacy, more detail, just more? Do I need a crystal ball to figure this out or just a couple of grand to buy a used KSA-250a and try it? There are so many things to buy. I don�t want to waste money.
