I think the recording is a big factor in staging/imaging/height more than we care to admit. I do find it interesting how each recording in general is different in certain areas.
Before I bought the Ohm MWT'S omni's, I had this idea that because of the way the tweeter was pointed straight up at the ceiling, that music would be splashed all over the place and not have much of an image or staging to speak of. I was so very wrong on this account, and in some ways prefer the omni presentation to the "normal" Ohm speaker. Probably the thing it does give up to the normal Ohm driver config. Is the ability to have that same sweets pot no matter where you are sitting. You tend to have to be sitting more centered to get the affect, but my, what an affect it is. On some recordings, the omni can be a tad bit overblown or slightly un-natural in it's presentation, but it is a rare thing and again, more recording dependent. I typically have the "hot seat" anyway, so doesn't really matter much to me.
Either way, the Ohm's are just a lot of fun to listen to, maybe not so much the defining and spot-lit definition overall, but thoroughly and utterly enjoyable. I probably just enjoy my tunes more when listening through the Ohm's. My Magnepan with subs are maybe a bit more used as an analytical tool, but still very musical and enjoyable. Really a big toss-up at times, I enjoy them both for different reasons I suppose. Tim
