Thanks all. It's what I thought but great to be able to get some quick advice here!
Balanced Streamer/DAC to Unbalanced Preamp
My streamer/DAC (Lumin D2) can output both balanced and unbalanced, preamp (LTA MZ3) is RCA only. Is there anything to be gained sound-wise by using the balanced outputs of the streamer/DAC via a specialized cable or adapter? Or just stick with unbalanced from source to preamp?
