(1) Preferrable to use coaxial or optical input w/ the DacMagic, rather than the USB? (2) Any sonic advantage between coaxial and optical? (3) If I continue to use coaxial or optical, should I disable Kmixer? If so, I could use some clear instructions.
I'm not so sure about number one. It seems that USB is all the rage these days, so I would suggest reading up on that a little more or, better yet, it's a cheap experiment to try both and see which works best.
Cruz123, In a recent follow article in Stereophile magazine, a series of test results on the DacMagic were published. The author concludes that there was significantly more jitter w/ the USB input- he recommends using either the optical or coaxial inputs.
