Is there a link to these tests? I am curious what other speakers they compared them with and what music they used.
Harman is an impressive company and I trust their testing protocol to be rigorous. However, they are a "for profit" company and I think it is reasonable to expect that they did this experiment among themselves before bringing in non-employees. I would expect them to select the other speakers for comparison that would reflect best on their speakers.
The OP could do much worse than the Infinities, but they had a fair amount of cabinet resonance when played at decent volume, resulting in muddy bass. Comparisons between the Pioneers and the Infinities I have read consistently favored the Pioneers...and that is before Dennis adds his skills to the AA version.
By the way, I owned both of these speakers (Infinities and Pioneers) and listened to them for several days in the same room at the same time with the ability to instantly switch between them level matched. Here are my comments from that comparison:

When we are talking about speakers in the $100-150/each range available for convenient return to the local big box stores, I would bet many people have taken them home and A-B'ed them in their own room.
The OP should do this, but he cannot as easily with the AA's.
And just so you know I am not alone:
