Got my SS2 setup yesterday and I'm floored how much my CS2.4's improved. I expected "more of the same", but playing with the Integrator and changing from augmented to crossover at 50Hz, the speakers took on a completely new dimension. Even smoother, the sound stage got completely 3 dimensional (you can easily pinpoint instruments not only to the left/right, but height as well and front/back).
I could not be happier with the combination of the CS2.4's with the SS2/Integrator.
