Need help with Blu Ray upgrade

If the Krell HTS has five analog imputs and does not convert to digital then try it both ways and see which one you like. As listed above the oppo se only upgrades the analog sections and uses a different DAC.

I was not sure how I wanted to connect the blueRay player so I bought the Oppo 83SE.

I received my Oppo BDP-83SE DVD player and I have tried it in my Home Theater system. It is going to stay. The picture is great what can you say it is BlueRay. Sound-wise it is better defined in the center channel than my Denon DVD-9000. I think the Denon had more air around the notes though. They are both using the same Krell processor with a coax. You would think they should be the same. I did not try analog because I do not have enough interconnects to hook up the Oppo player analog. I will buy some in the future.
Since I can not compare them, my Denon DVD laser quit and will only play CDs. I tried putting the Oppo BDP-83SE into my big stereo tube system against my Mark Levinson 2 piece. The Oppo is good but in a system of 40 tubes it can not hold its own. I guess it is not really fair comparison because it is apples and oranges. The Mark Levinson beats it all over and especially in the mid range. If I could make one change it would be a smoother mid range. I was using the same Audioquest Diamond x3 interconnects for both adjusting volume for single ended and balanced.

Your choice of the Marantz BD 8002 is a great choice. The Denon version(DVD-3800BDCI) will also fit the bill.
