YMMV but I had a pair O2 mk1 with a Headamp built KGSS (which I would consider a pretty good amp) and I found them dark, and that's basically why I got rid of them.
My understanding is the 800E is designed to work with special Nikon software on the computer to get rid of the issues pointed out. That makes it a PITA for some people's workflow in particular but I'm pretty sure the issues mentioned there will be dealt with.
Feel better Shelly
I did a Sunday group ride which for me was group in name alone as I was off the back nearly the whole time. Feel fine but could not ride for shit.
My work upgraded my laptop from 2GB to 4GB of RAM and it's honestly like having a new machine. So much better. Had not realized how badly it was choking before.
