Sophias are small but soundstage like large speakers a la Watt Puppies with more musicality (vs. wp6). May not have the ultimate level of detail and low, low end but are pretty close to the 6 ( I haven't yet heard the 7's). They are probably one of the most coherent speakers around, more so than any other wilson (other than 7's)and are quite involving, wickedly dynamic and image extremely well when set up right. I drove mine with Krell 750 monoblocks and they loved the power, so if you have hi powered tube amps or a good solid state amp, these speakers will not punish you. In fact, they can sound great with even a low end receiver but will reward you when you move up in amplification. They are the perfect $15k system or $50k systems speaker-they're that good. I'd rather take them over any speaker in the Revel lineup. I have, however only heard the Salons, which I felt were a bit edgy, whitish brittle and sterile. Overall uninvolving but technically impressive. JMO
