That's an easy one. Sonically, the Rogue 99 is much better. Also, in the after the sale factor, IMHO, Rogue Audio has figured out how to answer phone calls, have a conversation without bragging about their product endlessly, and last but not least, repairs are handled on-site by the people who build the units. AA can't claim any of the above. Art from AA has a reputation for being one of the rudest people around. Just ask anyone who owns a AA unit and had the misfortune to have isent it back for repairs long it took.
