can anyone name a speaker for half the wp's price that does not show it up?...sonically
Is this what you mean?
Or, did you mean, "Can anyone name a speaker for half the wp's price that DOES show it up sonically?"
I can honestly say the Von Schweikert VR4 Gen III HSE come very, very close to the sound of the WP7, IMO. No, they are not as good, but at their original retail price of $5995, it'd be damn hard to choose to spend an additional $15k on the WP7.
Also, Egggleston Andra II are excellent competitors to the WP8. In fact, I can easily imagine some listeners preferring the Andra II in a blind listening session.
That said, the WP8 are truly outstanding speakers, and probably worth their asking price for those who have the scratch.
