TagNplay and Elyric are the same. Most consider USB compromised. If you had the DAC MK II update, because the signal will now go through the digital lens via USB it should be very close if not the same quality as the Bridge. Most people involved would claim the Bridge is superior and the preferred way to go. If you don't upgrade the USB route is not as good as the Bridge method. This is one of the main advantages for some to upgrade to MK II status, that and of course the MK II sounds at least twice as good as the original. I've listened to both at the same time in my system, and there is no doubt in the superiority of the MK II upgrade.
