I have a pair of SM45s, Marimbas and Pioneers (bookshelves and towers. None are remarkably better than the other. The highs are a bit smoother on the Definitives and Marimbas or so I recall. In January I developed a hearing problem (Menieres Disease) which causes my hearing to be okay one day and crummy the next. Before that I would have to say the Asend's were the pick of this group. My brother has a pair of the 170SE. They are not the prettiest things for sure. I have the Marimbas and SM45s in original boxes and would sell either at a very attractive pricing. I am using JBL Studio 530s for 2 channel stuff and PSB for surrounds.
