Trying to decide b/t 5 used speakers w/ Rotel Amp

I currently have found 5 speaker pairs in my budget and would like to know how they might sound with my Integrated Rotel 1070 amp. (100 w/ch x2) Here is a list of what is on the market:

Vandersteen 2ce
Green Mountain Audio Europa
Thiel 3.5
Monitor Audio 8i
Axiom M22ti

Any help would be much appreciated.
