I'm having more time with A2C and I had some good sounds out of it, I wouldn't call it broken anymore as at least some tracks sounded good. A2C's bass is actually nice. Atmospheric music and similar calm stuff sounds good but "action packed" music sounds worse. I'm also not a fan of its vocal performance.
I also A/B it with Elegia (both driven by DX220 AMP8 - 4.4mm VIVO cable / $100 4.4mm Arctic Cables Elegia Cable
Elegia is better. Actually I am not super satisfied with Elegia and find it a litte bit overrated at its own. But compared to A2C it has bigger soundstage (both still nowhere near open backs) and much more clean/ fluid sound. Elegia has brighter more energetic tone but the "high frequency grain" problem of A2C is not present with Elegia, interestingly.
