I've been searching, but perhaps my newbie's limited understanding is preventing me from finding an understandable answer.
I'm wondering if there is a portable headphone amp with internal DAC that will accept the digital output of an iPod (a 160GB Classic, in my case) and processes the signal with its own DAC.
I just recently learned that it's possibile to extract the iPod's digital signal before it passes to the iPod's own internal DAC (i.e., products like the Pure i20 dock). So I'm wondering if the same thing is done by any portable headphone amps. I'd appreciate any answers. Thanks a lot.
