I don’t know if I can help much. I am looking at the nd8006 also. I need a CDP, and streamer. I have a tube integrated on back order that should be here in a few weeks.
New amp doesn’t have a phono Stage or DAC, my current one has both. I just can’t find a better option for the money than the 8006. I have looked at many combinations, but it gets more complicated (and expensive)than I want to deal with quickly. I know most Marantz product are not the “end all be all” products for everyone, but I don’t have a golden ear either. A good amp, some well matched speakers, and the 8006 with my Rega P3 seem like a pretty good system to me.
The 8006 has all the flexibility I will ever need . I have always liked the Marantz sound from what I have heard. At some point I may consider a DAC upgrade, but that would probably do it for me.
I have seen the 8006 for $1099 for open box with full warranty, have you seen it new in the box for $1100, if so where?
