There are plenty of DACs that can connect via USB that do not require third party software though. Why is it needed on the Burson?
Good question !
Conductor is using a special USB module, not a simple USB connection with a simple USB convertor.
USB module inside is looking very much like a
M2Tech HiFace
They are using custom drivers for their hardware, generic USB drivers of Windows or Mac OS are quite good but are not made for accurate audio reproduction, that is why serious DAC manufacturers are using custom drivers and custom USB modules.
Burson Conductors USB module also is also
not powered by USB power (5V), but by a separate discrete power supply, that is a lot more stable than the PCs noisy 5V USB connection.
USB module also has a low noise clock and a jitter reduction circuit, so in this case custom drivers is the best way to go if you want a no compromise solution.
For the 2 weeks that I had the Conductor, I have compared it's USB connection to a HiFace EVO powered by EVO power supply (battery power),
and Conductor sounded as good ! That is a great achievement in my book, as EVO + EVO power supply is among the best transport there is.
