I have heard both through B&W 600 series and liked both. The Marantz was worm with more head room. The Pioneer 74 had tighter sub and more fetchers. I have no need for HDMI right now. (70% Movies 30%Music) They will be running Paradigm Studio 60s front L/R, cc-470 center, 40s rear L/R and Seismic 12 Sub. I got to here the Pioneer through this setup but not the Marantz. I like the Paradigm's over B&W's. Which one will sound the best through this setup?
