I have learned from Roger Dressler, at another web forum, that the coaxial digital output downconverts everything to no more than 48-24. Including blu ray and DVD-A. Plus, the Gen 8 seemed to sound much better on DirecTV starting about 9 last night, coincidentally after being used or on standby for about 100 hours. The manual warns it needs 100 hours warmup - but I didn't realize that applies to a unit already burnt in but that was off for a while. So don't jump too soon to conclusions.
