Is there anyone out there who has comparison shopped the Athena AS-F2? I am looking at the Klipsch RF-15 for about $400, and I see that I can get the Athena AS-F2 for about $360. Which is a better speaker for clarity and brightness in the mid-to-high range (forget the bass aspects for now), and regardless of price how do they compare? Or, just opinions on the Athena?
