How to connect Firewire Weiss 202 and Firewire HD
Hi,if I'm running out of a 2010 Mac Mini with a firewire port, how do I connect both my firewire hard drive and then the Weiss 202 DAC vis Firewire? Do I just run from the Mac firewire out to the Hard drive, then daisy chain via firewire over to the Weiss DAC? Or will it be better for me to use a USB hard drive connection and connect the Firewire out on the MAC directly to the Weiss 202? Thanks.
