Feel free to enjoy any audio gear despite measurements telling you otherwise. There are interesting arguments to be made as to what exactly those measurements tell us, and why they might be the way they are... but the bottom line is that we like what we like. And there's nothing wrong with that. Don't let a chart or a number on a spec sheet tell you how to listen.
As for the original PS Audio DirectStream DAC, this is in fact a great deal. Despite being "older" by now, it's still a great sounding device.
