What is the better unit between the Anthem AVM 50, and the Marantz 8003 pre/pro. I am not really concerned with video processing as I am with the audio. As far as I know the Marantz decodes HD audio codecs and the Anthem does not. Stereophile Magazine article states that the processing of HD codecs in the AVR is not an important issue as it will be output at some point anyway as PCM 7.1 audio. If you could give me any suggestions to this topic, I would appreciate it. Thanks!
