the benefit is that they eliminate or minimize the effects of the S/PDIF interface. Usually, there is a USB interface chip that does some small buffering, but the USB data rate is much higher than the native data rate, so that when the data gets reclocked and sent out of the chip in the native data rate, the jitter is very low. Mostly a function of the crystal oscillator and PLL in the chip. This oscillator can be a Superclock2 for instance, making it very low jitter indeed. I believe it is usually a "push" model with flow control.
