No EQ solves what I've heard with HS50M, the built in EQ just muddies the highs but doesn't make them right, the weird character just remains.
Unfortunately I can't give you any clues about dynaudios, because I haven't heard them.
All I can comment is:
ADAM S3A (a bit bass light, but overall my preference)
KH O300D (smiley faced compared to adams, not so defined midrange, nice bass though)
Yamaha HS50M (ugly highs, forward midrange and high bass that makes beats more impressive, 1/8 of resolution of those highend nearfields)
Small cheap KRK (almost balanced, no ugly highs, about the same resolution as yamaha, nice for the price, nice for some concept/compose work in the field, but as your only monitor? I'd wait a bit and buy something more detailed.)
Behringer Truth (nasal with poisonous highend, nothing in the middle and than some sub boom to make it sound bigger, I'd rather quit working with sound than having rely on it)
Event 20/20p (old piece, it had some nasality built in as well as mud instead of midrange, impossible to judge HF, this box did't let a lot of character through, making things to sound alike --- yep I had them for a while
)
There are some success stories with Adam A7 and I'd try new genelecs (8030 or 8040)...
