I don't know about the AVM30, I've only heard it a few times, but I have compared the Anthem D1, to the 990. The D1, was cleary, and I mean clearly a step above the 990 in sound quality. I would love to do a blind test. The D1 brings things to the next level, but look at the price.. you have to ask yourself is it worth the price? If I had the cash, yes.. until you have heard the D1, Lex MC12, or Meridian G68, I've heard them all you don't know what you are missing.. once again, however, the price. Unless you have very good speakers, it's a waste of money IMHO, hence, 90% of the world would be pleased with the 990.
