Oh yes, indeed. I perceive the IE 800's soundstage as being wider than the IE 80's but with less depht. The IE 800 however has got the sharper instrument separation making the soundstage more precise.
I would describe the IE 800's soundstage as sitting in the first row of a concert hall whereas the IE 800 is more like standing on the stage of that concert hall.
As someone stated one page before, the IE 80's bass way more prominent in the mid- and upper bass and getting quieter towards subbass (with the screw being turned fully to the left). when turning the screw fully to the right, you get more subbass (level will match the midbass) and also more midbass, accompanied by a raising lack of precision and speed of the (anyhow slow, soft and bloated) lewer frequencies.
Honestly, I can't listen to the IE 80 with any material that has got a high amount of bass or is being played fast.
The IE 800, while still having a prominent bass, moves the emphasis way more to the subbass area with also an emphasis of the midbass and highs which are smooth despite the emphasis (this is due to the two Helmholtz resonators smoothing out the peaks in the highs).
Speed and texture is very good and the lows hit surprisingly fast for a dynamic transducer.
Imo the IE 800 is no successor of the IE 80 as it has got a different tonality, different technial goodies (bass adjustment screw vs Helmholtz resonators smoothing the highs), is on a much higher technical level, has got another diaphragm diameter and is priced much higher.
