Rockitman, indeed the Playback Designs is entirely different. I may be splitting hairs here technically but upsampling on your PS Audio(which I have heard although not in my system) and the MPD-3 resampling from whatever the native sample rate directly to DSD is simply crazy good. The PSAudio (and most other DACs) will upsample in PCM to a higher rez PCM format....basically just moving the noise into a different frequency spectrum. Resampling from a native PCM sample rate directly to 1 bit DSD removes so much of what we dislike about digital rather than just moving it. My opinion only, but it is so different and analog like that I believe you would be pleasantly surprised.
best wishes and happy listening.
