Thanks for the advice Jdub39. I'm definitely using the xlr out on the Oppo so I can take advantage of the Oppo's dacs. I'm actually also using the multichannel analog outs on the Oppo for SACDs. I will definitely plan to try out the hdmi out for SACDs as well to compare the 8801 dacs with the Oppo's. I just figured I already had the analog cables from my previous setup and thought I'd just connect them all at once... I just ran the full Audessey setup and I've tried out a few bluerays (star wars 2, Dave Matthews at radio city music hall) at reference levels as well as an SACD (holst planets) and some vinyl (police, Chet Baker). I'm still getting used to the sound of the 8801 but so far I'm definitely getting the sense that there's a lot more definition in the sound and more control in the decay of notes. I've still got to figure out all the detailed settings for viewing and audessey, but so far so good! Any experience with burn in time for the 8801? I've noticed the 8801 gets pretty hot, even on my open rack, so I figure burn in time should be short... Will report more soon!
