That EQ graph does look much less extreme than the one you had for V1 (from distant memory).
I'm surprised you feel the need to boost the higher frequencies from about 5khz, but we all hear things differently. If you had the configurable Blaxius^2D BNC cables between HMS and DAVE, I think you'd be surprised by how different cable screening configurations can affect the need to EQ the high frequencies. I actually prefer the configurations that tone down HF, but this is primarily to more sympathetically handle poor recordings.
Regarding LF EQ, DAVE's Cross-Feed function progressively adds bass tailing off up to about 1khz. I find that CF=1 or 2 are fine (even beneficial), but CF=3 adds a touch too much bass.
Regarding the unravelling pads, yes this is why I still occasionally criticise hifiman for build quality: cheap synthetic cloth crudely glued to cheap plastic is bound to fail sooner or later. The pads sound good and they are very comfortable, but hifiman really should look at the (cheaper) Meze Empyrean for how to do it properly, including the superb magnetic release system for pad swapping. Nevertheless, my own SE pads are still fine (touch wood) and I'm very, very pleased I did the V2 upgrade to SE.
