Great DAC. You only want to use the SPDIF connection as that is the 24/96 input with the least jitter. That is the #1 preferred connection. If you need a USB/SPDIF converter, the V-Link 192 will get you there for $200 new and you will be very happy with that combo (I had that before I went to a DSD DAC...to try DSD, not because of any other issue...and I kept my Bolder DAC).
Good luck with your sale...
