I've owned Otello's for over five years and your description of their midrange doesn't match what I hear. I would suggest however that you get them farther off the wall behind them. In my current room which is 17'x 26' the fronts are almost 6' off of the wall behind them but in the last room which was only 14' x 17' the fronts were 4' off the wall. If you haven't, look at the placement calculator online in the newest Othello manual and try those calculations as a starting point.
speakers that are a little laid back in the mids
I'm just curious what full range speaker people have found where the mids, voices etc are not so up front. I have had my share of speakers and some I considered to be very good but over time seem to be on top of you. Not necessarily harsh however. My room is 13 x 16 and I have used tubes and ss.
