I ordered mine yesterday around noon. It got delivered today just after noon. Not bad, but I am in San Diego which helps.
First very early impressions after an hour of listening or so:
Apple Macbook Air -> Wyrd -> Hugo -> Lyr 2 -> HD800(stock) and Paradox Slants
With Wyrd, the highs seem less strident. Smoother, but not darker. Just less harsh. As you can imagine, the HD800's on the Lyr 2 can be pretty harsh and bright. On recordings that are prone to sibilance and pain on some highs are actually not sibilant and bearable using the Wyrd. The difference is more noticeable than I expected. I am sure I could tell in a blind A/B test.
Apple Macbook Air -> Wyrd -> Geek Out 450 -> Lyr 2 -> HD800(stock) and Paradox Slants
In this case, I think there's even more difference. It's wyrd though that the output level seems to be louder when the Wyrd is in the loop. That doesn't make any sense though, but maybe the internal volume of the GO changes when I plug it into the Wyrd vs. the Macbook USB port. The difference is basically the same as with the Hugo, but I think there may be more bass impact with the Wyrd. On the highs, it's definitely smoother and less harsh with the Wyrd.
Anyway, I figure if I can hear the difference, then other more experienced listeners will definitely hear it and be able to describe more accurately the difference.
Overall, I think it's worth the money. I don't have anything like the OR5 to compare, but I don't think I'd listen anymore without the Wyrd in the loop.
