I am going to sell my K240DF's and get another set that YOU guys recommend for my specific use, which is to act in place of (as much as possible) real studio monitors (Genelech's?) in a music mixing and mastering studio (whew).
I've got $400 'studio monitors', so I'm looking beyond just getting clean sound - I need an accurate reference to mix music too! My current monitors have no bass, and my 240DF's (I have just recently learned) are for a different application.

I've heard nothing but praise for the 240's but I don't know the difference between the 240M and the 240's. But I'm leaning at one of those two since I've heard them mentioned the most.
thanks in advance.
