The Wolfson DAC chip used in the Transient does not have a DSD input.
We are working on a higher-end model that will accept DSD through USB, and also have several coaxial & toslink inputs, dual Burr Brown DAC's, 32 bit volume control, selectable digital filters, single-ended & balanced outputs, digital display, and full function remote.
This model will be much more expensive (somewhere around $2000) and won't be available until later this year.
