That hardly seems like a fair contest. I wonder how the Sonata compares to the VR-4Sr.Apples and oranges, 9rw. The choice--for me--would come down to the type of music I prefer, the amp I want to run (the Sonata III can easily be driven with a 7W SET amp), and the room. I find the Sonata III, which sounds nothing like the Sonata I or II, to deliver an astounding level of refinement. It does not go as deep as the VR4Sr, but the tonal resolution on the Sonata III is up there with the best I've heard. Alan Yun (Silverline prez) brings emotion from the Dynaudio drivers in a way I've not heard even from Dynaudio's speakers.
Caveat: I've not heard the $25K+ Dynaudio speakers.
Hope that helps.
