There weren't too many DACs using 1394, only dCS and Weiss come to mind.

One problem with SPdif and AES/EBU was that their protocols only allowed the transmission of data to 96kB/s. So, in the case of dCS, IEEE1394 was used to carry DSD data between their component boxes. However in this role the Firewire interface was poor at transmitting a stable embedded clock signal so an additional word clock connection was also required.

The revision of SPdif and AES/EBU to enable the transmission high rates of data has obviated the need for 1394 for DSD transmission use.It also allows the use of high sample rate PCM data as well of course.

There are also practical difficulties in sourcing decent sounding Firewire cables for audio use. Few specialist audio cable manufacturers produce cables to support the standard and the use of computer cables for audio use was/is, in practice, pot luck. As few computers now use Firewire the situation has not improved.

For computer sourced audio the ubiquity of USB also played a major role in the demise of Firewire
