Just wanted to ask computer folk what they would recommend when using a MacBook Pro in a digital based audio system.

I am intending to use it hooked up directly to a DAC via USB or optical. What ripping software and file management software would you recommend on a Mac?

My Mac has a 320G HDD but was wondering if I could attach a 1TB HDD via USB and run files of this.

I intend to rip all CDs and only use a file based system.

Any help or suggestions would be appreciated.
