Brian,
I have compared the Ascend CMT340 against the Philharmonic Audio Affordable Accuracy, and honestly, unless I absolutely needed the extra SPL, I preferred the Affordable Accuracy - it sounded more neutral to my ear.
A $210 speaker out performing a $500 speaker may seem strange, but if you consider that the CMT340 is more or less a CBM170 with the extra SPL and efficiency from the second woofer, you see you are paying a lot for the second woofer (including larger cabinet and associated shipping costs).
To me, the Philharmonic Mini-Monitor with the world-class RAAL ribbon tweeter offers a substantial step up over the competition.
However, as BSA mentioned, you would definitely need a sub with the mini-monitors and if you really like to listen loud, they may not be what you want.
You mentioned looks and neither the Ascends or the AA's are anything special to look at. The Mini Monitor is definitely a step up on that count.
Wharfedale makes fine speakers and while I don't think they offer the value of Philharmonic speakers, I think you would regret them.
At $320/pr, the Klipsch RP-160m is not a bad option. I really feel that Klipsch made decisive improvements with their new RP series. I have a pair of RF-82 ii's in my HT and feel they got left behind when the RP series was introduced. Whereas I really don't consider the RF-82ii a good music speaker (I'm pretty picky and have some nice speakers), the new RP series impresses me for music as well as HT!
Personally, the Elac B6 and Uni-Fi just sound dull and disappointing given all of the attention they have received.
