So I have a mixture of audio gear, some balanced some unbalanced. My DAC, which is VERY nice, has only balanced outputs. The pre-amp I am looking at has only RCA unbalanced inputs. So does getting an adapter to take the balanced and turn it into unbalanced defeat the purpose of having a balanced output in the first place? Is it actually degrading the sound or hurting it in anyway due to converting it from one connection to another? Same goes with my amps. My AVR that I am looking at hooking up external amps to has only unbalanced RCA outputs, my external amps have only balanced XLR inputs. What should I do?
