Let's Fire It Up
My test bed is currently running an ASUS Xonar alongside the Auzentech board for quick comparison between the two.
I am using an external CD player running digitally from itself to the Prelude via coax, and then out again via toslink optical (24-bit/96k) to my Logitech control centre. What this really means is I'm using an external device to test the card as opposed to an internal optical drive, and that I'm doing it 100% digitally.
Above is an image of the provided toslink optical cable which is used between the card and my Logitech control centre. Also included are two adapters that convert the coax ports on the card to toslink optical. The Sample rate is selected via the control panel with either 96k or 48k to choose from, although as I have mentioned before, other factors affect the actual real world sample rate aside from the choice made here.
