DPLllx can decode audio recorded in 2 channels into up to 7.1 channels and can decode 5.1 audio sources into 7.1 channels. I guess it depends on your setup and how you listen to music or HT if you will use it or not.

By my experience, most of the people you may call for one of these online sellers won't have a clue what you are talking about. I bought mine from Etronics a few weeks ago and was told they did not and by another that they did not know if they had the newer receivers with the DPLllx. I took a chance and mine does have it. I would think by now, most or all should have the newer versions. Good luck.
