Just looked up the Devore Silverback since you liked them better than the mighty Vandy 5. This is one speaker that does not get any press at all, how did you find them in the first place.
Give us more detail, what makes them better than the Vandy 5? Drivers on the Devore Silverback look high quality source from Denmark, what is unique seems to be in cross over. Have you compared to other speakers using similar drivers to get a sense of how much improvement is really from the cross over?
