Not an exact answer, but after hearing Wilson Watt Puppies in several shops and shows, the Transparents did the absolutely best job (especially taming the WP "scratchiness"). Sorry, never heard the Sophias.
As the owner of WATT/Puppy 7 and WATCH Surround I'd have to say the JPS Aluminata's. The Transparents are pretty damn good, but the Aluminata's are a tad better!
