i've come up with three options, but would still love to hear from the experts here!
1. theta casablanca has a analog direct (matrix) mode (pure analog to mains, duplicate signal created and crossed to generate sub channel);
2. use a y-adapter on the main (L/R) pre outs on the SSP to route signal to both the power amp and sub;
3. my dac (Wyred) has multiple outs so i can route the main signal to the SSP using one set of outs and to the sub using the other.
