Hi
Yes i am aware of this feature in Pioneer as i owned the VSX 520 ...the first 3 D model......
This is there in Marantz as Multi Channel Stereo...all the speakers play with stereo effects......
If your current AVR is working fine then you should not change it unless you want some new features or different sound signature.....
You should audition other AVR brands with the same brand / model of speakers and use the same playback content as in to draw a reference...
