Hi everyone. I'm Looking to develop an upgrade path for my home grown server before it's too late. Currently I have an early 2009 mac pro. Firewire out to a Weiss INT 202 interface. That gives me balanced out to a DAD AX24 dac. If I were to replace the Mac Pro, which model mac would be appropriate? Since firewire is out, would adapters work to connect to the INT 202? or is USB better now? Your thoughts would be appreciated.
