Actually I'm just trying to be more cost effective in my setup. I know of course that I can use the Denon to achieve my goal, but my Denon receiver will be in the living room and my M80 is in my bedroom with the DAC. I can run cable from my Denon as second zone to my bedrom, but I'm still in stereo mode without a sub. Initially, my quest was to figure out how to get a sub into the second zone (stereo only) that I was planning on setting up. Now, I'm stuck into this DAC odyssey. After all the considerations I'm gonna get a stereo preampt with sub out. Thanks for your input.
