Most DAC’s with a FireWire interface are pro-gear.
Few brands address the consumer market.
The TC Audio DICE chip is often used for the Firewire connection.
A lot of Firewire DACs use adaptive mode just like their USB counterparts.
Other than Metric Halo all the Firewire protocols work the same way adaptive does. That means any company using TC Electronics Firewire (From the Oxford set).
Only Metric Halo has an Async Firewire setup, everyone else is not.

Mytek claims their Firewire interface is async.
The Duet2 is USB only.
