mrpotto,
that's a great deal you have going with your dealer!!!
Maybe you can tell us sometime later which Dynaudio speaker that was. I think that BW and Dynaudio make my personal favorite dynamic speakers that I have heard.
I wish I had the opportunity to hear Totem. Their good reputation precedes them. However, they are definitely known to have lower sensitivity, but there is variation of this spec within their lines. Depending on room specs, distances, you might need to consider your amplification. Perhaps not, but maybe.
If you get them in (or just at the store w/ your BWs), you probably should level match, because the Totems will most likely sound quieter for the aforementioned reason.
