I auditioned the Eos and Eos HD. I have hesitated to report on it, because the experience fell so far below expectations that I'm inclined to blame it on dealer set up. I had expected to buy the speakers, because they were an excellent on paper match with the room I had then, and Roy was so helpful. But I, and the non-audiophile friend who went with me, couldn't wait to get out of the demo. "Forwardness" indeed; I'd have characterized the upper registers as "edgy," or "brittle." I read one UK review that was consistent with my impressions.
Now I should say that I am one of those people who is overly sensitive to brightness in the highs, and numerous well-liked, highly "detailed" audiophile speakers are torment for me. But I would say that if you have this issue, it might be wise to approach the Eos with caution.
FWIW, I found the HD to be conspicupiusly better than the base model, though the my issues remained.
I should stress, since I've been a bit critical, that YMMV. As I recall, Shakeydeal went to GMAs from the Montana's I now use, and likes them much better.
