I'm not very familiar with the Sophias, but have enjoyed the WP7's for their delicacy with Lamm SET amplification. I currently own the Indras, and I find them to be very musical and balanced, excellent sound staging, reasonably fast. I'm very happy with them. They are not particularly strong on the bottom octave, though not bad. Originally I purchased a Fathom 113 sub, but haven't been using it lately. Perhaps the Indras are breaking in, though I think I'll hook it back up once I get through various system modifications I'm currently doing.
