If you want to try an Anthem and don't need the extra features of the D2, consider using an MRX 300 as a pre/pro. That's what I'm doing, and it's been working great. I figure if the technology changes in a few years, I can just replace the MRX and still be out way less than the cost of just an upgrade to the D2. You get a slightly watered down version of ARC, but it doesn't sound like it's worth the difference in cost.
Just get something that has the number of inputs and outputs you need and don't worry about the extra features, there's better ways to get streaming, Netflix, etc. Apple TV, Oppo, Squeezebox, Dune, etc.
