Okay, now I understand (hopefully correctly) that there are two kinds of jitter - converter (difficult to measure), and data (measurable in a DAW).

Now, I'm seeing a LOT of numbers thrown around.

Black Lion claims their mods produce 7-10 picoseconds of jitter on the clock.
The Apogee PSX-100 is 5 nanoseconds - that's 500 picoseconds.
The Mackie Onyx800R is measured in a review at 7 nanoseconds.
RME's steady clock (which is, arguably, comparable to the Big Ben) is approximately 2 nanoseconds.

What's going on? Why are the Black Lion specs about 50x as good as the Apogee?

Are they measuring something different than what we're seeing posted elsewhere?

Help?
