To Doug Schneider,
My CD player and DAC have RCA coaxial and TosLink optical connectors. Which one is the best to use?
In general, audiophiles favor the coax over optical because it usually has lower jitter (i.e., less timing errors). In reality, though, it also depends on the implementation with each component. Therefore, to really know you’d have to try each one out. . . . Doug Schneider
