External Sound Card with Logitech Z-5500's

Hi all,

I am going to be building a mini-ITX system in a few months and will be getting rid of my large ATX board. This means that I will not be able to use my old Creative Audigy 2 that has served me well over the years.

Right now I have the Z-5500's hooked up via Digital Coax (kind of reminds me of a 3.5 mm male connection) and 6-Channel Direct (orange, black, and green cables). I was wondering if I purchase the following external sound card, will I still be able to hook my Z-5500's up via Digital Coax and 6-Channel Direct?

I am willing to look at any other external sound card options that will support the Z-5500's.

Thanks for any advice.
