I'm fairly new to this whole recording thing. You must be someone who is doing a nice living out of this. But it's still besides the point.
You say my opinions are lacking common sense (well it might, mostly because my English I guess)... but you still are knocking blind tests. If you take a look at the debate that's going on here on GS or different forums, there's really no AUDIBLE proof about jitter. But you and your colleges can easily hear it, and the difference is big. But you are not willing to prove it nor do a double blind test. To me it just doesn't make any sense, no matter if I'm not a super pro...
And remember, I'm not saying that you guys weren't hearing a difference. But the difference most likely wasn't about the jitter.
