I use the analog outs from my Oppo BDP-83 Blu Ray player directly into my McIntosh MX120 processory. That way I take advantage of the new sound formats offered on BluRay because the Oppo does the decoding. I does take some adjusting on the trim levels from movie to movie though, especially the bass. The coax signal does come quite close to the new audio formats but I'll continue to experiment with the analog out method and won't be using the passthrough on the BDA-1.
