I've owned a "Sr" since they first came on the market, and have been very happy with it ever since.
Paul from PS Audio says the "Jr" is "85%" as good as a "Sr". I've heard both, but not side by side. The "Sr" in my opinion seems to extract a bit more detail from the source, and to me, sounds just a bit more "analog" than the "Jr".
Both models have been improved over time with PS Audio's release of new firmware.
If I were in your shoes, I'd wait and get the "Sr".
