That's interesting. I never knew Best Buy would have a set of iFis, since they aren't on the website, and none of the Best Buys in the Bay Area around me (around 4-5) have ever sold anything Klipsch other than the 2.0 Ultra, 2.1 and 5.1 Promedias. I also can't find anything online about BB deals for the iFi, unlike that for Costco, which are quite prevalent.
How much do they sell them at the Best Buy you saw? The full $400?
I do find the comparison you made funny.
"iFi? Nothing compared to bookshelves!"
"want PC speakers, get Logitechs!"
Sounds like Anselm's ontological argument for the existence of God where he keeps interchanging the definition of "greatness."
