I was in the same spot about 8 months ago. My forum thread is HERE if you are interested. After months of researching and watching reviews, and chatting on these forums, i finally made up my mind on a budget setup.
I end up getting the 58X, D10 Dac, and JDS Labs Atom Amp. Cost me a about $450 CAD + Tax. I am very happy with those 3. The headset was lacking a bit of bass for my liking, but an EQ fixed that. Now i’m looking to upgrade the pads on it to make it more comfortable. Later i also added the Antlion ModMic Wireless to it to make it into a gaming headset. $150 CAD +Tax
