Speaker Upgrade

I am looking to upgrade my speakers in the used market. I am considering The B&W 803D, Sonus Faber Cremona M, Dynaudio Confidence C-2, and Usher BE - 10.
The room is 20x20 with 18' ceilings. They will be mains in a 5.1 set up for SACD's, audio Dvd's and home theater. They will also be used when 2 channel listening. The amp is The Emotive XPA5 at 200x5.
Your input will be greatly appreciated!
I am heading to Overtures and Hi Fi House this evening.
Soundex is appointment only and it has been tough nailing down a time.
Put off by window shopping.... are you serious? They put in a cd, give me a remote and walk away. Such is business.... if their prices are reasonable I will buy. How do you select gear? Do you send someone thousands of $$$ without listening?
I go to shows, listen to other's systems, etc. If I go to a shop to audition gear, I go with intention of buying if I like the gear. I don't try to compare the prices of new gear from those with overhead to the prices of used gear from those that don't have the same overhead. If buy used gear and like it, I keep it, if I don't like it, I sell it. I try to treat others as I would like to be treated.
Taters Yes I use a Rel B3. Really sounds great.

Pkelly1504 I would ask to hear some speakers and once you ask the price you can always ask about pre owned or demo.
Xti16, wouldn't it be more honest to ask about pre owned or demo pieces first, if that's what your in the market for?
