Damon,
Thanks for the great time and the opportunity to listen to your World Class Palladium 39F's.
A few thoughts!
To describe their sound is tough! It is unlike anything that I have heard.
Without a doubt these seem like the smoothest Klipsch's I have heard from Klipsch ever.
The top end is very sweet. Some credit of course is due to the Aragon 2005 amp which is remarkably smooth for SS IMO.
Mids were very defined some would say very close to neutral perhaps the best Klipsch has come up with ever.
The bass was very taut, with very good pitch resolution.
When listening to rock I felt the Palladium's had a great sense of
focus for its bass line resolve you certainly could make out many parts
of a drum kit easier than many other types of speakers.
Interestingly SWL was there briefly and commented very strongly that he felt they needed the subs. An amplifier, preamplifier with greater warmth might alleviate that sense of need like the Peach II that SWL owned and auditioned in my system it has a lot of warmth of course there are many other alternatives.
But in the end its all about your satisfaction and no one elses.
The cabinets are beautiful and there are no resonance issues that I could tell of. They virtually disappeared.
Overall the speaker shows a lot of promise.
Certainly I think they are a world class speaker capable of serving music well with the finest of electronics Tube or SS.
One needs to audition them with a variety of electronics I'd certainly
would like to hear them with a variety of tube gear and better digital,
Like the Rega CD player that had substantially more body and warmth which seemed to served the music
better IMO.
Finally in the end, My hats off to the Klipsch Engineering Staff! Well done 
Thanks Again for the fine grilled brats you are a Grill Master!
