You state you are not a Polk fan, yet you are thinking about spending $1,100 on a pair of them ?
You need to make a list of new speakers in your budget. Research what stores you can audition them at. Take a few CDs you like and are very familiar with and listen to them. Make notes about what you like and dislike about each pair you listen to. Also note what they are driving them with.
After you have whittled the list down to a few pairs you like, research what owners have to say about them. Listen to them again but bring different material along - some "test discs" if you will. Bela Fleck's Flight of the Cosmic Hippo will stress all but the most capable speakers when played at an elevated volume level.
If you aren't completely enamored with something at the end of this process, you need to increase your budget or start looking into used gear.
You likely will have these speakers for quite a few years. It is worth the time, money and inconvenience to check them out carefully before you put down your hard-earned cash.
I'm with Travis - my ears say older SDA Polks are pretty hard to top from a performance standpoint, especially in the bass region. However, I do know my ears also really enjoy ribbon drivers like those in my AL-IIIs.
Good luck with your quest. It can be painful, expensive, tiring and frustrating. But, when you find that right "something", it is well worth the effort.
