I just recently had a very similar discussion HERE. I was looking for a good solution for amazing sound quality for music, and also good sound stage and imaging for gaming.
In the end here is what I end up buying:
Topping D10 - Dac
JDS Atom - Amp
58X - Open Back Headphones
Antlion Modmic Wireless
And in the future, I plan to also buy the Argons Mk3, and maybe DT770 32Ohm for my on the go headphones to listen to music off my phone.
Still waiting for the 58X to arrive, i can post my feedback here once they arrive.
