Coaxial or fiber optic i/c for Dolby Digital?

My experience tell that the coax always take the trofé. I have not heard a optic beat a coax in sound reproduction ( I´m talking sane comparisons ). An optic in same pricerange as coax has really no chance. Less ´musical´ is the proper word.

Regards

I use a computer as my source, and so prefer an optical cable over non-optical so as to prevent all of the electrical noise present in the computer from being attached in any electrical manner to my DAC.

If your fiber is Toslink forget it and go coax.
