Rooms do matter. Also consider trying speakers with less toe-in. Most speakers are actually not designed to point right at your head. Also try listening below the tweeter firing line. Often you'll find a much fuller presentation that way.
Special Forty?
So, I am an unabashed fan of Dynaudio. I recently purchased a pair of Special Forty's with the stand 20. At first, I thought...wow...did I make a mistake? I added more sand to the stands, I changed their position several (read hundreds) of times, and even "tried" to rearrange the furniture. All with the same outcome. The sweet spot was miniscule. It was there, but boy was it hard to find. Then, I did something smart. I moved them to an appropriate sized room. And I again thought...wow. but this time, in a completely opposite and positive way. Oh my gosh. These speakers (when placed in the appropriate room) are an amazing addition. I absolutely love the sound they produce and the imaging is wonderful. Rooms matter. Room treatments matter. And these Dynaudios will be staying right where they are. My favorite new spot.
