I want to use a Spitfire DAC, but how do I convert my USB signal to a signal the Spitfire or any other DAC will accept? Put this in the correct forum if this is the wrong place.
With any USB audio interface which has a S/PDIF digital output. About the cheapest one on the market is a Behringer U-CONTROL UCA202 which can be had for 22 pounds in the UK dunno how much it is on the other side of the pond.
