We've actually discussed studio monitors a little already. TheSloth posted one that had a really flat frequency response -- M-Audio, I believe, and it was supposedly really cheap. I haven't heard it though. I also bought TheSloth's Quad 12L powered/actives, which suits my office quite well for enjoyable listening. I'm not sure how accurate they are. He cursed me by telling me they had a midbass to upper-bass bloat, which I now hear, but it's not as intruding to me as it was to him, so I don't mind it so much. I intend to eventually pair it with a sub -- probably a SVS SB-12Plus.
But I don't think I've discussed much my favourites -- the Mackie HR824's -- really dig those, they're sort of the Sony MDR-V6's of the active monitor world -- too bright for most people, but perfect for monitoring, in which case you need revealing equipment. I actually don't get tired of their sound too much.
If you're going to use a sub, they've since introduced the HR624's, which are probably perfectly adequate.
Which Dynaudios did you try, the BM5A's? I've wanted to hear them...
I've also owned KRK V8's, which I really regret letting go, they sounded pretty good. But I hardly ever used them, so the regret is minimal.
A musician friend of mine uses...um...Alesis's, I think. Or maybe that's the amp? I think they're Alesis passive monitors, too, now that I think about it. They sound alright, but what's good is that he makes really good-sounding music with them. Link.
Are you getting these for pleasurable listening, or for studio stuff? IMHO, that makes a big difference.
