A killer rig driven by your preamp (what I use anyway) is the Schiit Magni 3 (Now the "+") for $109 combined (or not) with their Loki Mini +...get the nice small "Pyst" cables (made by Straight Wire) from Schiit to hook 'em up and that should blow away nearly anything else for small bucks. A great sounding rig with EQ.
