While I'm not saying you should jump on the 805's, your comment of them reminded me of something. I bought a new pair of 805S when they first came out and had the same response as you. No bass, and aggressive tweeter. All this after owning two pairs of Signature 805s.
What I found is that the characteristics you described seemed to disappear after about 250 hours. I'm wondering if your demo pair was broken in?
On another note, I haven't heard the Proac with Sim, but have heard and believe that it is probably a good combo. I'm a little surprised you didn't find the dynaudios pleasing
