How big is your room? The reason I ask, I have the Thiel CS6's as well as a pair of the Thiel SS2 and a Thiel SI 1 Integrator. I tried using the SS2's with the CS6's and ended up with an excessive amount of upper to midbass energy. This was of course using the SI 1 in Augment mode where none of the bass signal was being cut from the main speakers. When I connected the SI 1 for Crossover mode I had to adjust the cut off frequency up to around 75hz just to tame all that energy.
Keep in mind that these were placed in a haphazardly way and no where near optimized for the room but you knew just a soon as you heard it that something was not right, might be awesome for home theater guys.
But I can say with them in the same location and a pair of Thiel PCS in crossover mode they sound awesome. I have the PCS's placed right beside the CS6's and I actually had to take the cut-off frequency to below the low frequency limit of the PCS's to get them to sound correct, like down to 50hz. Yes I know that's essentially Augment mode but I already had it connected in Crossover mode and didn't want to rewire everything.
If you happen to live around the DC area we could work out a time frame for a listening secession and I could bring a sub or two for a sampling.
