Any time a digital signal is converted from one format to another there is some opportunity for audio loss / colouring. As such, a coaxial (it's not technically RCA) digital connection has two less conversions, being electrical digital - optical digital then optical digital - electrical digital.
Regardless, the loss/colouring will be absolutely minimal and most likely inaudible.
