Are there any advantages of using a usb to spdif converter if you already have a spdif output on your computer, or is it just for those that don't have an spdif out and own a dac that doesn't have a good usb implementation?   The reason I'm asking is that I plan on buying a Schiit bifrost...

Hey guys, I need help!   Currently, I own a pair of D2000s, and I recently decided to get a better amp for it.   I'm stuck between buying an AMB M^3 (w/ Elpac wall wart) and a Matrix M-stage.    Which amp is better suited for the D2000s? Can someone who has listened to both amps help...
