I actually own the Mg's and have them paired with the Topping A30 D30 Pro, and must say this pairing sounds great with the MG's. The D30 Pro having a more relaxed signature really tame the shoutiness.

Thanks for the thoughtful review. My musical tastes align with yours. I would appreciate if I could have your recommendation for a suitable mid to high end headphone for metal/hard rock and sometimes jazz. I am currently listening to FiiO m17 with Tia Trio and would be keen to have a similar profile in over ears. I sold my Ether 2. Even though the detail retrieval was second to none, they sounded a little…safe and bland!!
