Thank you for the reply, I did look at that device before posting however I am looking for a line-out or a line-level device as I have both a stereo amplifier and a headphone amp.

A headphone amp/DAC wouldn't be undesirable either in that sense as that signal can be taken as line-level as well 👍

It also depends on if you're using a filesystem capable of compression.  If you are, you can use a smaller card and still hold a lot of data.  It's like putting your entire filesystem in one big zip file.

Hi, i build it on ubuntu 14.10.
