I purchased a DAC which has both optical audio and coaxial audio inputs available to it. It also has a USB audio input which I thought might be the way to go if I was only traveling a short distance to the DAC. However presently I am using a USB repeater cable which goes 82 feet over to the other side of my basement from my computer where I intend to do my music listening. The DAC I chosen has its own internal power and consequently doesn't rely on USB power through this 82 foot cable, but I thought perhaps the voltage swing at the end of this cable may be less than optimal. Perhaps it's optimal enough to satisfy my DAC which hasn't arrived yet. But if it isn't here is my question.
I wish to know how to add either earn optical audio output or coaxial audio output to my computer which now has none without buying an elaborate soundcard which would make me purchase a lot soundcard on board circuitry which will not be used. So are there either good quality conversion USB to optical audio converters or the same for coaxial audio output? Or the same for cards which will plug into one of my desktop PCs card interfaces? I would like it to do minimal processing just convert output to either optical audio or coaxial audio or both with minimal processing and minimal undo expense.
