It has a very similar sound to the W4S's DACs. The biggest differences I found were in the low end and overall dynamics. The Wyred unit has a more powerful low end, while the Burson's low end was a little thinner but slightly more articulate. I also found the Wyred unit more dynamic overall. Both are fantastic sounding units, but it's a little disappointing that the Burson unit doesn't have a remote and or balanced out either. There are other small technical differences, but you would have to study the literature on both units to compare.
