Harley's review also had a sidebar comparing the WP7 to the Sophia; I'll have to check it out at home tonight, but it was along the lines of very similar, not quite as refined but you're not going to be giving up much with the Sophia, if I remember right. Having heard all three in my dealer's showroom on a few occasions, I'd say that the Sophia is surprisingly close to the WP6, giving away just a little in refinement but not much else--no wonder they had to do a redesign of the 6. The WP7 is a step up, though, the first Wilson WP that I'd consider buying, as it manages to have a big sound (no more miniature orchestra) and surprisingly good bass extension, as well as a level of transparency and ultimate ease that the Sophia comes close to but cannot match, in my limited listening to the two.
