I disagree entirely, but that goes to show you how people hear sound differently

I found the athenas to be about the worst of the bunch in my auditions just passable for some music, and mostly geared for HT. I can tell you right now that the midrange on the infinities is many times less colored. Simple plotting of an FR curve for the 2 speakers would further show this.
Just an FYI, stereophile gave them a rave review:
here is a snippet:
"1) The natural and uncolored midrange of the Primus 150 rendered all male and female vocals with a rich, natural, holographic sense of realism and body, without a trace of coloration. On classical and jazz recordings, woodwinds, pianos, and acoustic guitars were reproduced with natural attack and decay, with harmonics into the extended, natural, and airy high frequencies.
2) The levels of detail resolution and low-level dynamic articulation of the Primus 150 were unheard of for $200/pair. This attribute, combined with the Primuses' ability to disappear while reproducing well-recorded works on a wide, deep soundstage, may make the 150 the speaker for classical music aficionados who cherish the reproduction of concert-hall ambience. Moreover, the speaker is very useful as an analytical tool; I could analyze the articulation of a soloist's style as well as decipher multipart instrumental arrangements.
3) Although low- and mid-bass were inaudible with these speakers, the quality of the upper bass was reproduced with extraordinary clarity and authority."
