    This statement is imprecise and incorrect. You can not compare a data format and software protocol (S/PDIF) with two different types of physical connection: either electric 75 Ω using a 3.5 mm RCA plug (coax) or optical with corresponding cables, plugs and sockets (Toslink).

    Aware of the technical differences Werner.

    They both are digital connections to a Dac, my ears can hear music from them both.
    Think the OP was asking more for subjective opinions from forum members on which one they thought sounded better.

    That was mine.

    these are not technical differences, but semantic ones. You might be able to hear a difference between a data connection/transmission via an electrical 75 Ω coaxial (RCA) cable and an optical (Toslink) cable, but there simply cannot be any difference between Toslink and S/PIDF, as you claimed earlier:

    Was meaning Spdif as in coaxial connection...vs optical Toslink.
    Both SPDIF as you said.

    I would suggest that the issue is one of nomenclature rather than semantics per se!

    For me in my system the best option is coax. I have tried optical and it wasn't good generating lots of drop outs however, that was quite a few years back with a Beresford DAC so it may be worth re-investigating it.

    Iím happy with S/PDIF via optical connection (Toslink), but my Macbook Pro and iMac donít offer coaxial digital out. Toslink works without any dropout or other flaws, with various Beresford as well as Schiit DACs to which I switched later.

    It pretty much depends on the individual kit, my Stello CD Transport has AES (XLR) and SPDIF (Coax) outputs plus i2s (BNC), I was surprised that Stello recommended the coax connection over the AES, but having tried both, I agree with their recommendation on this particular device.

    I thought optical spdif was supposed to be more prone to jitter, so coax spdif is usually the better choice, all other things being equal?

    Properly implemented, they all sound pretty good though, I wouldn't like to pick between any of them in a blind test, USB included.
    So it boils down to how well each is implemented on your device/s as to whether there is any audible difference, rather than hard set rules, so a bit of suck it and see.
