I'm not real up on the bass management on the AVM-20's multichannel analog input -- based on the review's comments, it sounds like they are offering the option of converting the signal back to digital for the processing and then back to analog. Maybe I'm a purist after all, but that doesn't overly appeal to me. If you can get your hands on an AVM-20 and do some listening tests (which I suspect you can, if your shop carries Anthem), I'd suggest demo'ing a couple of DVD-Audio or SACD discs (Blue Man Group has some good bass to experiment with, but it might be good to test a disc without much bass so you can look more at any loss in sound quality), turning the bass management on and off to see what affect it has.
