Here's the question. I have an older Marantz integrated amp w/dolby pro logic, driving older Klipsch speakers. I am considering upgrating to DD/DTS, etc., but wonder if there is any way to utilize the marantz in a new set-up. Excuse my ignorance, perhaps there is no way to do this. The Marantz does NOT have any main-outs. It just seems like a shame not to be able to use this in any way. I love the thing for everything else it does, but want to upgrade to the latest, greatest. As always, thanks.
