in this case any of the options mentioned will work just fine. think about your budget, buy the best thing you can afford.
I own and can wholeheartedly recommend Dynaudio, Genelec, Harbeth. I use
Dynaudio BM5 mkIII as my main studio reference monitor. I love them and have had them long enough to really know them well. I’ve recorded and mixed many albums with them, and I like just listening to music on them as well.
I use Genelec 8010A+7040APM in my art studio and they are also great. If I had space and didn’t need it to be ultra-portable I would have gone for the 8040 without the sub, but this setup lets me easily move it to new locations or use it for temporary installations. The sub sounds great for listening, but is hard to setup for critical work, and I’d almost always recommend larger full range monitors over a sub for anything critical. I partly got the 8010 because I do multi-channel sound art and if I need 8-10 of these I can rent them and know what they will sound like.
In my main listening stereo I have Harbeth C7ES-3’s. These are absolutely phenomenal—balanced, expressive, and just a pleasure to listen to for hours and hours. IMO they are also revealing and flat enough that I could definitely use them as studio monitors. However, if I was going to get this style for a monitor I’d go with the Harbeth Pro series or similar since they are voiced more specifically for studio work rather than home stereos.
If I was buying new main monitors now I would consider the Genelec 8040 or the 8340. The digital room correction is very appealing in the 83xx series. And although I love my BM5mkIII’s, I’m not sure I love the current range of Dynaudio options quite a much as the previous models.
