I use a Thiel S1 integrator for stereo and a PX05 for the surround channels.
The 3.7s don't need the sub for most music, but in a large room, the SS2.2s are so well integrated with the 3.7s in terms of pace and speed and adds that bit of tactile bass for some instruments (double bass etc)
I also have a JL Audio f113 and it's a tad slower than the 3.7s. Don't get me wrong the JL is plenty fast compared to other subs. But the SS2.2s are just so well matched.
I used a reasonably well made but cheap shielded XLR cable for the subs. Silversmith XLR for the stereo power amps.
