I am considering selling my Denon 2801 (which is used as a preamp) for the 2802, if PLII is worth the upgrade. I primarily use my HT for watching TV and it seems that 98% of shows only use the center channel, and if they use the rear channels it is very minimal. Does PLII really help out that much? Will my surrounds actually get used while watching TV. FYI: I use DirecTv for locals and premium service. Thanks.
