I have this in my system now for about two days. Inside pictures later when I can figure out how to open it up and get my camera back. It is stock, not modded by John Wright.
I've been comparing it with my also Parasound DAC1100 (using Squeezebox 3 as digital transport).
The Bitstream is definitely on the same level as the 1100. The Bitstream has more presence in the upper mids which opens up the Omega 2 a bit. The high freq extension is also exceptional on the Bitstream. I will run some test tones later, but right now nothing is missing from the highs. Bass might also have a bit more oomph, but this is too close to tell at this point. Both the Parasound and Museatex are exceptional digital, not just at their respective price points.
