Mattnshilp, I used to greatly favor Firewire as the best connection and even had a FW to SP Dif converter. Then Apple who owns Firewire totally pulled the rug out from under it and third parties that made converters. I also used to greatly dislike USB even with asynchronous clocking within the dac, but now I have heard many USB connected dacs that sound quite good. I must say that USB cables are greatly improved. The BMC USB cables is the best I've heard.
In my case, the greatest concern is high definition. SP Dif is too limited to PCM and USB is not. That is the end of my interest in SP Dif.
