There is still a bit of lingering glare though, not sure if that will pass with continued burn-in, or if its a result of poor synergy with the Pico. I'm thinking a powerful, dynamic tube amp would pair best with these, from what I'm hearing so far. They seem to possess an innate vibrancy that would be enhanced even futher with tubes.
The Ed9 is actually starting to remind me a bit of the O2, when driven by the 007t. The O2 was more tonally rich, and also somewhat darker, with mellower highs and less immediate dynamics, but there seems to be a similarity there to my ears. Has anyone else ever thought this about the Ed9 and O2?
My Edition 9 took around 100 hours to kill the glare from the APS V3 cable, and I had the Edition 9 fully burned-in before re-cabling.
The Pico is not the best with Edition 9, but it isn't bad either - I thought the bass was slightly less controlled vs Predator, but not enough to be worth selling the Pico for a Predator. It shouldn't add any glare - it's the cable needing another 48-72 hours of running in.
As for O2, you just described more dissimilar things than similarities
I don't recall any other headphone sounding like an Edition 9, and I heard O2 on an ES-1, Woo GES, and SRM-1 Mk2 Pro and liked the Edition 9 better.
