I don't know, but I sure wish someone here could compare, say, the Emotiva and or Primare, VS USING AN OPPO DIRECT FROM IT'S ANALOG OUT'S - bypassing an external pre/pro, and using DD/DTS and internal processing in the OPPO - DIRECT TO A MULTICH AMPLIFIER FOR MOVIES AND MUSIC!!!
...lay this thing to rest, for goodness sake, why doesn't someone?!! -tired of hearing audiophiles say they don't think they need a preamp at all!!
LET'S GET A SHOOT OUT GOING! My 2 cents
