Well that was interesting!
I certainly don't consider myself a golden-ear type, but it is very difficult to find obvious differences with the normal set - you really have to hyper-analyse the tiny details (differences which no-one would care about in a non-comparison shootout of course), or just go by "feel".
My procedure was to load the tracks into Logic, with MetricAB on the master bus and the raw/dry file loaded in there as the "B" reference. So I could just flip between whatever track I wanted to play and the raw file.
I did some rough notes of the normal set, then ran through the heavier set.
Overall I tend to prefer F which was a little brighter and I think is the characteristic of the SSL Native.
B I'd guess at the Townhouse which is darker and thicker - I think it's autorelease behaviour might be a little slower than the G bus. D might also be a contender for the Townhouse as a second guess.
G & H were probably my next favourites in no particular order, with J in fourth place.
There were a few which sounded a little clamped, C maybe, also K. E was also a bit brighter which I liked.
But really, I figure they are all pretty much in the ballpark of what a G Bus does, with F and B for me being the ones a little different (in a good way, F brighter, and B thicker.)
I don't really have much experience of the other plugins of hardware to start to attach guess for each file.
One definite takeaway is I really liked the track!
I'd appreciate the cheat sheet, thanks! (And thanks for doing this.)
