First of all all of the speakers you are considering are truly excellent. I own kit AN/Es and have previously owned the DeVore Super 8s. The DeVores are among the most musical, enjoyable speakers in existence at any price.
You are correct that the AN/Es are more dynamic - actually either Audio Note speaker is. As wonderful as the DeVores are, dynamics is not their strong suit IMO.
You are also correct that small rooms *can* be an issue with the AN/E, which is very extended and can put out a lot of bass.
IMO all these speakers are at their best with SETs. In a small room, a 2W 45 amp is plenty for the AN/Es. The DeVores are happy with a PX-25 or 300B, or even 2A3 in a small room.
Finally, 2nd the recommended on the Sistrum stands. They are excellent.
