It is said that coaxial has several advantages over ordinary TOSLINK
connections, a greater bandwidth being one of them.

Problem is, coax outputs are generally driver through a special lossy
transformer that rolls response off above about 12 MHz to reduce EMI.

IIRC, TOSLINK has barely 7 MHz of bandwidth.
Have to look that one up, though. May be old information.

For parts like this - TOTX 111- yes - Toshiba quote 6 MHz in fact
