Large room but not large budget-suggestions please


We are moving to a new house in December that will have a fairly large listening room (about 22x25)with a 2-story vaulted ceiling. I originally posted this question in the amp forum a couple months ago when I thought I would be moving to a similar sized smaller room and could upgrade amp and speakers but that is not the case now. My budget is $1000-$1500 tops.

We listen mostly to Classic Rock, Jazz, Blues as well as some vocal and classical. Most listening is moderate volume. We currently have a Cambidge Audio Azur Integrated (60wpc)and some Altec bookshelves. The speakers will not be doing HT duty. I am considering the Totem Arro's, Monitor Silver 6, Vandersteen 2Ce Signature, and Revel Concerta F12's.

I know I should probably upgrade the amp as well as speakers but the budget will only allow one for now. I want to get the most bang for my buck and I'm thinking that the speakers will make the biggest impact. What are some opinions on the speakers I'm considering, are there any better ones (used/Audigon) is fine.

OK, I had a chance to measure the room today during the inspection. The dimmensions are 23Wx18Dx20H. The speakers will be along the 23' wall and we will most likely sit 8-10 feet away from them. The floor has carpet but the rest of the walls are drywalled. The ceiling is vaulted and open to the 2nd floor which is a loft on one side of the room only. Given the measurements my guess is that I should be looking at the same speakers (higher efficiency floorstanding) as before, right?

You may find this article interesting and possibly effective in your situation. I found myself in a similar situation. Large room (22 x 24), small speakers that are designed for a room less than half that size (Audio Physic Spark). I tried a zillion different speaker placement methods. The problem was always a thin presentation with little bass weight. Then I read this article, talked my wife into the idea and applied what I read and have been very happy ever since.

Good luck.
A quick update. Today I spent some time listening to the Totem Hawks and Thiel 1.6. Overall I'm fairly sure I liked the overall sound of the Thiels over the Hawks. The Thiels seemed to have fuller, more engaging sound. That being said, will the Thiels work in my larger room with my current amp? Also, since I am going to try to listen to the Vandersteens, do they have a similar overall sound as the Thiels?
Another update. We are moving into the house this coming Friday (finally) so I am getting closer to making the decision on which speaker to get.

I was able to listen to the Polk LSi15's and liked what I heard. They put out a good soundstage and I heard details in several of my demo CD's that I hadn't heard before, alot like the Vandersteens. My concern with the Vandersteens is that they have the full "acoustic sock" fabric which might be an issue for our two cats, even though they are front declawed. My question is has anyone done a side by side of the LSi's and Vandersteen 2ce's? How are the Polks/Vandersteens and as far as room placement goes, easy or hard to get setup properly? Also, given that my Cambridge integrated has 60w/90w into 8 and 4 ohms, will I really have enough power for the size of room or should I be looking at upgrading the amp as well, and if so, what are some suggested 2-channel amps that can be added to the pre-out on the Cambridge?

I know, alot of questions, but any help is appreciated!
