I used to have the same thing.....2 systems in one rack. I also had the SMS-1 and whatever amp I had at the time running a VMPS Larger for the .1. The one thing I truly enjoyed about this type of rig was that if one setup didn't work for a particular genre of music, I would just power down and power up the other one....adding the sub in when needed. If needed for certain rock, I'd run the entire rig. It ranged from 8 watts to almost 3200 watts depending on the gear I had at the time.
I'm sure that rig has given you many hours of listening pleasure. Rock on bro'.
