Ok, here's the deal i have built my computer server i wont bore you with what the build was other than it has a asus xonor stx sound card. This question is about my music componants, i have a sunfire 600 watt amp and a sunfire pre-amp. Problem is the pre-amp has no digital input, so im looking for a new pre-amp. I was thinking the benchmark DAC1 HDR. I welcome any and all sugestions.
