I have owned the AVM-20 v2 (along with a Rotel 1068, and an Parasound AVC-2500) and traded up to the D-1, which I currently own. While there is a point of diminishing returns, I am very happy with my decision. While some of the feature sets are similar there are some that set the D-1 apart. I think the right processor for you will depend on what speakers you plan to pair it with. If you have full range (or at least go lower than 80 hz (THX standard)) for fron and rear, you will hear a benefit from the D-1.
The major difference is the D-1 had 24 bit/192 kHz DAC's on all channels which for me was the major benefit. I had my CD players going into a Musical Fidelity A 3.24 into the AVM-20, and straight into the D-1 beats it for me. The D-1 is airier and more detailed. So if you listen to a lot of music, the D-1 could be worth the extra $$.
The D-1 has dual digital processors, which doesn't make a huge difference at this time, but will when the new Hi-Def audio formats come out, and makes it more future proof.
The upgrade for the D-1 will also include a video scaler, which won't be in the AVM-20 or 30 upgrade packages.
Either way I think that anthem is a great way to go. They continue to have free software updates, and support their products for years. The bass management is far superior on the Anthem processors compared to the other models I have tried. I have never heard the Parasound C-1 or C-2 though.
Hope that helps,
Don
