XDA-2. If you don't play vinyl, do you really need the preamp in the path? XDA-2 has remote with volume and input switching. Mucho digital inputs and real balanced output stage. Balanced out to Sunfire amp? On top of that, the XDA-2 volume control uses a resistor ladder type that is really pretty darn good. IMHO, this is a better dac than DacMagic. I have used both in the past. Plus it has an IEC socket so you can try aftermarket power cables that DRAMATICALLY IMPROVE THE SOUND of this killer little dac. Don't use an integrated amp as a preamp Randy.
