I have an GDA-700 DAC hooked up via RCA outs to my system, and very happy with it. I've now got two systems set up. For the second one, I've fed it from the analog outs of a CD player, but I would like to run this second system off the DAC as well. I don't want to run them at the same time, but I'd like to leave the hook ups in place. The GDA-700 has both balanced (XLR) and unbalanced (RCA) outs; the manual is silent about if they can both be hooked up at the same time. Seems I could use a Y-cable (or solid adapter) to split the RCA outs to send to the two systems. I expect some signal loss if I do that, but I believe there is more than enough output (voltage) from the GDA-700 to make this work. Alternatively, I could use an XLR(f)-to-RCA(f) adapter (Hosa makes some) for the second RCA connection. My understanding is that the Hosa XLR(f)-to-RCA(f) adapter grounds the pin needed to turn its RCA output to unbalanced. Is there any advantage of doing this one way or the other; that is, will having both the RCA and XLR outs hooked up simultaneously, or using a splitter on RCA outs, cause any issues? I'm not concerned about a lower signal level due to a split, but I would be concerned if either set up would cause a degradation of other aspects of the signal quality. I'm including a sketch of the schematic for the final outs.
