I at least will agree with Rbstehno that the cp-6311's are very good. But weight isn't the only consideration when it comes to evaluating or enjoying speakers. As for halving prices, you are talking used versus new, apples and oranges. A new pair of CP-6311's are $2100. It is difficult to find the Epos used because they are a fairly new model and people aren't parting quickly with the ones they have.
I have not compared the Epos directly to the Ushers, but I have compared them to well respected models from Naim, Totem and Rega, and the Epos stood up very well in that company. I also have compred the Ushers to Rega speakers, so have some common currency.
I think it is a matter of taste. I would say the Ushers have a nice, smooth treble and mid-range, and strong bass (more so with the CP-6311). In contrast, the Epos has a very well integrated sound from lower mid bass to upper highs, with (to me) a sophisticated view into the details and timing of the original performance. So IMO, both pairs of Ushers sound nice, while the Epos draw me in.
