I settled on ESP-950 as a long term setup after listening to nearly every high end option on the market circa 2015.

Once you achieve minimal distortion and can EQ to taste there's really very little difference between open cans in my experience. Minor differences in soundstage, maybe.

Then Raal released the SR-1a which to me seemed like it might actually be a step function upgrade due to the difference in presentation having significantly higher involvement of the pinna. Been enjoying it but damn is it placement finicky.
