Hi - this is the manual:

Here is the replacement adapter?

Would this work the same as the original supplied with the Xonar DX? I don't know why they are calling it a mini plug...

Is there a better place to buy this?

I buy the exact same cable to connect my Asus sound cards to my external DAC/Amp.
so, yep it will work for you and the price is nice.
