Hey URS,
Well a few months in, I'm still very happy. I actually listened to the A/B yesterday with an engineer friend and he was blown away with the difference.
As you said I think accumulatively over a mix there is alot more space and depth with a bunch of Green tracks say compared to the 002R tracks.
I think you will find them quite different from the ISA, though I did test them against the old Focusrite Green series pres and in a blind shoot out of voice and trumpet 3 of the 4 engineers chose my Greens over the Focusrite.
You can't beat the Green Pre, it is something I think I will always have a use for. I'm actually racking up another 4 I recently built.
And those clips had no special A/D, just straight into the TRS inputs on the 002 interface.
Cheers
Matt
