I am not familar with the OP avr, but some elite avr's PQLS function is for 2 channel only, like my SC 35. The SC 37 is multichannel. Sometime the function has to be cut on, off, and back on with my SC 35 before the light on the BDP 430 comes on. I can tell a difference in audio quality, although it is a small margin of improvement. You will not notice it or miss it unless you are switching it on and off with the same source. I brought the BDP 430 for the PQLS. Overall, my Samsung BD 5500 3D player is a better player. More apps, faster, and can play more formats.
