Floyd,
I run RCA from the pre to the SMS, then RCA out to my main amps and on to the Parsifal monitors. I also run RCAs from the SMS to my subs. This utilizes the 80hz roll off for the Parsifals.
If I decide to spring for a Marchand X-over, then I'll run a separate pre-out to the Marchand, by passing the SMS in the main signal path. For the bass, I'll still run through the SMS, out to a bass amp, and onward to the Encore woofers.
I believe that the SMS does A to D, for PEQ in the digital domain, but I'm honestly not certain. Since I've so far dealt with frequencies below 80hz, I'm not all that concerned. Whatever damage A/D does, in my room, it is dwarfed by the benefit of the PEQ at these frequencies.
If I want to cross to the Encore woofers at 150hz through the SMS, I'll find out if this favorable cost/benefit can be maintained up to those higher frequencies. As of right now, I haven't tried it, so I don't know the answer.

PS I fully understand the reluctance to add A/D to a minimal path, "purist" analog system. This recent experience has convinced me -at least on a preliminary basis - that, for deep bass, it's worth it.
