Help with Audio Set-Up

[MuncherKid]

I'm looking for a new and better audio set-up or around $150 (not including headphones). I dont want to use cheap converter (such as RCA to 3.5mm to not use DAC or Sound card). I already own the ATH-M50WH. Here is what I'm considering.

Bravo AUDIO V2
FiiO D3
ASUS XONAR DG
3-Feet RCA Cable
6-Feet Digital Optical Cable
