There can be a difference, and you can hear it. Optical goes through another step in decoding, so they are not the same, and a lot of how well an optical handles this is based upon the quality of the RX/TX optical signal decoder, that can cause the process to create a more "digital" sounding soundstage. Usually that's due to the quality of the optical transistor in the RX part as well as perhaps transistors that follow in the signal path. In essense, something happens during the decoding process by inferior optical decoders to take away the smoothness capable with a good quality digital coax.
