Have both the HiFiMan Edition X & Sundara and the AKG 702.
The HiFiMan Edition X pairs nicely with a Mjolnir 2; the Sundara pairs well with Magni/Piety?Vali 2+ stack. Magni 3+ and Magni+ versions win here with Piety close.
The Sundara were wonderful out of Mjolnir 2, however the Edition X now has that place.
The Edition X plays nice with the Magni/Piety?Vali stack and scales up to the Mjolnir 2 better than the Sundara.
The AKG 702 I purchased to complete the way back trinity - Sennheiser 600/650, Beyerdynamic DT990/880 600 ohm and AKG 701(702).
I never found an amp paring or music that the AKG did better than the others. They hung around mostly unused. Piety came along and after a test run of phones I found the 702 enjoyable powered by it. Maybe I changed or maybe I found their thing; either way they now get some use. Would like to try them out of a Jotunheim 2. I have a Jotunheim OG and the Piety wins.
All above is my music, my gear and importantly my mood/health/condition/ears.
PS - The XS were a HiFiMan repair upgrade offer I could not refuse. Considering Arya.
I love my Sundara with my Asgard/Freya stack. I found them to be overpowering in a wall-of-sound way with the Piety. I'll have to try them with that amp again when I get back home in early November. My HD650's and Thieaudio Ghosts are, for my ears, perfect mates to the Piety/Magni 3+/Vali 2++. To try something different, I pulled the trigger a few minutes ago on the AKG 712's. If I don't like them, back they go and the Arya's will be purchased. I've also eyed the Edition XS. I love my Sundara so much that the Arya went on my wish-list a few months ago.
Cheers,
