Another Paradisea+ owner here. I do not have the USB version however. Currently just have it connected to the CD player via coax. Leaning towards the Trends UD-10 with the battery pack for connecting to the computer.
An Acer running Windows Vista. Vista improves on XP, and all older versions of Windows, by eliminating k-mixer which was what all the driver workarounds focussed on. Basically Vista is just XP without the extra hassle audio-wise. I've been using Vista since July without any complaints. If you can go Mac do it. I'd also go I2S, but the solutions here tend to be very expensive for what you get.
Some more expensive DACs including the USB Benchmark use I2S eliminating the need for an external connector. BTW the Paradisea is preferred to my $1k NuForce processor. I am using the Bendix tube and a tube damper rather than the cheap stock tube. It's also worth noting that the consensus view is that the Benchmark is very good but somewhat analytical, some people prefer the Lavry DA-10 or Monarchy NM-24. Also, you mentioned the SN DACs as well, just didn't make the cut for me, but the price is pretty good.
