Is there a portable amp for the HD800 that is equivalent to the Eddie Current Zana Deux S or the Blue Hawaii or can come close to comparing with them?

Looks like Chord Hugo & Astell & Kern AK240 are high as they get for portable rigs.
I don't think I read many posts praising the Hugo & HD800 pairing.
The Blue Hawaii is for Stax but if you are looking for totl performance in a portable setup then the answer is no. The HD800 is not something that the majority of the owners use in a portable setup either.
Ah...No....Not very portable. They are amazing at home with your TOTL rig though.
