I HAVE noticed that the IR is more directional on the 900 than the MX-500 to 850 series. I don't know if is the physical plastic window that is narrower on the 900 or the IR power itself.
Daniel hasn't done an "IR Power" test in a long time.
Time for another test........... and a few reviews......... and that CEDIA movie......... and........ Daniel, are you listening? Are you slacking again? (He knows I'm kidding about the slacking, kids!)
