I found a pair of the E41-B new in a box for $300. So I've decided that I'm going to audition the E41-Bs, the Peachtree Design 5 and one of the Philharmonitor or the Song Surround I. If the local KEF dealer has a liberal return policy, I'll likely audition those as well.
My concern with the E41s is that they may be too small for my 1500 cubic ft office. I think I'm going to try each of them without a subwoofer first, but in the end I'm pretty sure that I'll get a sealed sub from SVS.
