...I ownd a W/P 8 for a almost a year. The Sophia2's will give you 90% of the W/P 8's and in some areas, are more pleasing and enjoyable. The W/P 8's needs a powerfull amp or one with high current (ARC Reference 110 wasn't sufficient and couldn't control the Puppy's).
The Sophia2's can play music to a very high level with integreted amps such as Naim Audio SuperNait. I think that the Sophia2's are excellent buying. You can also consider Thiel 3.7 or Revel studio 2.
