Hi Jamie. Don't like bookshelves? No problem. I think your confusing biwiring (2 sets of speaker posts) with biamping (2 amps). Because you can use any single amp you want with the speakers I mentioned.
I do have some input though. My room is similar to yours 12x13, I listen primarily to rock and love a wide and deep soundstage.
This is my opinion only for what thats worth.
You can scratch Sonus Faber, Vienna Acoustic, Spendor and Vandersteen. More laid back type of speakers that do better with jazz and acoustic. Wouldn't normally be a first choice for some one who likes rock.
Merlin floorstanders ($10,000 new) unless there much older models are going to cost well above your budget.
Not sure, read some reviews, but I don't think the Silverline or Dali are really speakers one would associate with rockers.
Avalon, PMC and Ariel Acoustic I'm not familiar with.
The Tylers, B&W and Totems though can do rock and these IMO would be some good ones to check into.
There is a problem though.
First. A 12x12 foot room along with floorstanders is not usually a good mix. I figured by your post since you will be adding a sub you would be going with the bookshelf/sub combo that most use in a small room.
You will probably run into some bass response problems using a floorstander in a small room adding a sub may complicate this matter further.
Second if you want a big wide and deep soundstage the speakers are going to have to be well away from the wall. The rear of the speakers probably 30" or more from the back wall.
Third if positioned correctly for a large soundstage. The front baffle is going to be around 4 feet from the rear wall. This will put you about 6-7 feet from the speakers. If you do this you will need to probably look at a 2 way speaker. 3 ways, which many floorstanders are, are going to typically run into integrationg problems at such a near field listening situation.
Fourth and don't be insulted. But by your posts I think you might be new to high end audio and need to do some additional research before shelling out $2500 clams. You may come to the same conclusion that many have reached. A bookshelf, that can be moved away from the wall for listening, along with a subwoofer works better in a small room then a floorstander.
