I'm using upgraded D5k's across the front and a G68J. Neither my wife, daughter or I can hear any difference playing with Trifield width. We tried an iPod using an Apple dock as an analogue source first. I picked a couple of songs that had decent seperation and--no change. Then we tried a redbook CD with the Oppo again without any change. I really don't think anything is happening.
