Note that to process DSD upsampling you need a decent CPU and clean processing environment to do it properly. I think a lot of issues people are experiencing has more to with limitations with their systems than the DSD upsampling. If you want to try something different I highly recommend you give Daphile (www.daphile.com) a go. It is free, can be loaded from a USB stick, runs in memory, does not disturb your windows environment, and being Linux is very efficient in its processing. Also it does not require specialised drivers and supports a wide range of DACs out of the box. Well worth a try.
