I used to own a pair of the Dynaudio 5.4 and thought they definitely needed a sub and were way too revealing for my tastes. As long it is was great recording and most anything but rock, they sounded good but otherwise?
I also own a pair of Totem Rainmakers and love the way they sound on most everything but they cost a fraction of the Dyn's so not really a comparison but think I'd love to audition more Totem's if I had the chance.
