Those would work yes but be careful.
On a different note, I'm ending my chase of the HE6se white whale. Maybe they are too heavy, maybe I didn't like planars.
I've tried a million amps including the A70pro and the Schiit Ragnorok 2. It's not just power, something holds these headphones back to me, even with ample power.
I bought refurbished (2 pairs) and had to send one back within warranty, which they gave me some headache about, but ultimately they repaired it at their cost. I did have to make my case a few times sternly.
Obviously this is a personal result, not bashing the he6se headphones. At the moment I'm using fostex th900 pearls and can listen much longer and louder.
I feel like this is a journey everyone goes on.
