You should be proud of me.
I got my Russound system on Friday, and that night because I couldn't sleep, I went to my rack (about 0030) and pulled out the old Sphere, dead SMS3.1  and replaced it with two K2-C5 kits and DMS-3.1. I was done about 0730, just in time to show my wife how to use it.

Now for some disclaimers.
1. No wire management... yet
2. Only two keypads wired
3. Not all the speakers connected
4. I didn't want to go to the truck to get the RCA cables to run between two units, so only 1 source works on second unit.

But at least I named all the rooms in the software so that I could use the MyRussound droid app. Showed my wife how to use Pandora on HerMusic stream thru the app.
