I went through this same issue - heres the skinny after talking with Anthem direct:
The major diffrence between the D2v and the AVM-50v is the 24bit 192 KHz.
Neither are HDMI 1.4 certified. However, they say if you buy new prior to August 2011 (estimated certified HDMI 1.4 release date) they will send you the HDMI upgrade for free once released.
The D2v has multiple AD 1896 sample rate converters which upsample every channel of digital or analog-DSP input up to 192 kHz (including Dolby Digital and DTS-the D2v is the first pre/pro in the market to do this!) The DACs then do further 128x oversampling to raise the final sample rate to 24.576 MHz.
Cosmetics
Video processing in both units are performed by a Sigma VXP processor
Feature set in both units exactly the same
If Two Channel Stereo or Audio in General isn't your #1 concern, go for the AVM-50v. Anthem states you will not hear much of a difference.
