Currently using a pair of Ultrasone PRO 2900s, this amp and an Asus D2X.
 
Looking at spending £150/$240USD, plan on using the optical from the onboard chip on my motherboard. Just want to know what a decent upgrade to my Asus D2X would be in that price range. RCA Out would be a bonus.

I'm currently looking at getting the MA TubeMagic D2 or waiting and saving for the Schiit Bifrost.
 
Is the difference between the two significant enough to warrant this? Opinions/Ideas anyone?

I have heard the Asus Xonar STX, not heard the D2X. The tubemagic didnt seem like an upgrade to the STX.

I've been looking at: DacMagic 100, DacMagic Plus, Schiit Bifrost and the Firestone Fubar 4.
 
Which of these is the best and how big is the difference between the DacMagic 100 and Plus.

Nobody have an opinion on those DACs in comparison with each other?
