It has a mediocre soundstage in terms of width and height, the depth is not bad, i agree. It's standard Focal level. Focal never leaned into soundstage, that's Hifimans schtick. 1266 / HE1000v2 / Susvara are way bigger.
Light on bass? Hmmm, well, it doesn't have an elevated bass per se like a Stellia / DT1770 etc, but it slaps so hard with its macrodynamics. They are the very best of any headphone except the 1266. I would never EQ bass into it. I personally dislike too much midbass, since it often bloats into the mids and makes male voices sound very bad (MDR-Z1R and Stellia was way too much). I know that also drums live in there, but only because you elevate the midbass does not make the headphone more dynamic. I agree that the refresh is a bit of a joke, the Nutopia might be worth 5k€ in comparison to the other TOTL's, but not when you can get the old model for half the price used. Also they needed to switch to dual 3.5mm and could have altered the tuning more than they did (hooray, -1.5db treble). I will probably hear it at Highend Munich in may and have no desire buying one before that (and probably after haha).
Ha! You also have a D9200, an old Utopia and a Rognir. Nice. The TH900Mk2 would maybe be to V-shaped for me, i haven't heard it, i was close in buying in several times but got the Denon in the end. I dislike how it's much older and still pricey. I almost bought the white pearl version three weeks ago until i read that is has even more treble than the regular red one.
