Reply to Getting into production: Picking up HD-25 and thinking about MDR-v6 or Grado sr60i...

Hey guys quick question. Picking up another pair of the HD-25's (I sold mine and looks like I want them again!) for DJ'ing.

Now I've extensively read that the HD-25's can be thought of as reference monitors as well. Since I'm also planning to pick up a Maschine as my entry into production, would you say that I should also pick up a neutral set of cans for production? If I already have the HD-25s, can they serve both DJ and production needs, considering I'm also just entering the production scene.

If not, I was planning to pick up a good set of budget friendly production cans and after reading all the threads and doing my research, I've settled on the V6/7506 or even the Grados sr60i. Would love to own a set of Grados, but just wondering if the Grado open-ear philosophy is good for production (EDM/hip hop) ?

So basically 2 questions:

1) If I have HD-25's already, do I really need to pick up another set of cans for production?

2) How are Grados considered as cans for production? Which would you get: v6's or sr60i's?

Thanks!
