Thanks Freddie, that's about how I remember it, but seems like there should be some kind of db adjustment formula (like 30% or 40% or 50% each side etc.) in order to re-mix equally into the rears. I do notice that the info in this ES 7th channel seems to be unique, at least with this bunch of stuff; which most I believe are available in stand alone releases elsewhere. Still, I guess I should run the flacs through my Oppo 205 (analog outs) and see if it handles it correctly once I identify specific ES 7 (Rear channel Center) info.edit: i should add, just as with the Front pair, adjustments may need to be made to both the distance and volume settings of both Rears in order to get them to image properly back there
