Rcprince: Said it perfectly that the
The top end on the Sophia is more forgiving. I found the JC-1's will be a little bright (many hours listening to this amp even after the 1500hrs breakin) on the top but your CDP should take care of that edge. The midbass is warmer on the Sophia's. The WP7's require a more time to setup but that's what your excellent dealer will take care of for you! The highs and mids characteristics can be adjusted with a resistor pack from Wilson (The WP7's are amazing with the customizing and flexibility with the setup spikes for the Watt and the Puppy)
The other option is to buy the Sophia's and then buy the Watch Dog and you will be amazed! Or buy the WP7's and then do what I did a 1.5 years later.. I bought the Watch Dog which give you better positing options of the WP's!!
Another Deciding factor was weight as the 160lb Sophia is a lot harder to move around than the 100lb Puppy and the 75lb Watt which can be separated! Important when you don't have your friends around and you tweak a lot, but otherwise let your dealer dial them in!
Now I'm extra Happy! until I can upgrade to the Maxx II's and keep my Watch Dog.
No problems in your room size with either as my room is 12x16 and I ran them in a much larger room also.
Either way you will get an amazing speaker!! that will reveal everything (good or bad )! But your Electronics will present a good synergy.. Oh yeah.. make sure to run the JC-1's Balanced as the design is fully diff balanced and sounds much better, and run it in High bias for Jazz and female vocals and low bias for Techno and Classical (full orch)
