Did the choice to use coax over TOSLINK have anything to do with jitter?
Yes that too, here's the reasons why we did:
"TOSLINK has a couple of drawbacks that must be acknowledged and understood to maximize performance, however. First, the implementation of TOSLINK requires a change in format from an electrical to an optical medium. No such change, including similar changes from digital-to-analog or from analog-to-digital, is without cost. In the case of transforming the electrical data stream to an optical signal for use with a TOSLINK interconnect you will increase levels of both noise and distortion within the system. This decrease in fidelity may be especially pronounced with wide-bandwidth multi-channel signals.
A related drawback of the TOSLINK scheme is its tendency towards restricted bandwidth. Truncated bandwidth in an optical connection can cause signal interpolation and/or jitter, and thus compromise the sound. Selecting a high quality interconnect with a minimum 10MHz bandwidth ensures maximum compatibility with multi-channel sources such as a DTS-encrypted DVD...."
"...From the earliest days of compact disc to today many audio connoisseurs have considered the coaxial S/PDIF interconnect audibly superior to the optical TOSLINK format. Improvements in optical conductors have somewhat evened the playing field, but if your connection needs to be more than twenty feet or so in length you must consider the coaxial solution..."
