Ref30 is newer than the AVM2, which to me is an advantage. Anthem gives you balanced outputs, B&K doesn't. For most uses, that won't make any sonic difference. Now, if you're talking about the new Anthem AVM20 vs. the Ref30, that's a whole different discussion. You're more likely to find the Ref30 and AVM2 available used though, the AVM20 is still too new. The AVM20 bundles everything but the kitchen sink, and lists at $3200, while the Ref30 lists somewhere around $2800. I ended up choosing the Ref30 recently and it fits my needs pretty well. Not sure how the AVM20 would sound with audio, but it has just about every home theater feature you can dream of, and on paper it looks great... I suggest you find a dealer and personally evaluate products from B&K and Anthem.
