I disagree a little..A headphone both more detailed and punchy than the VC? I’m salivating over here.
I think the VC is faster and more punchy, but the Atrium has more textured bass due to its slower decay, making it perhaps more impactful.
And the VC is slightly more resolving, but the Atrium’s sound stage and tonality are superior.
No winner, just different characters. Atrium if someone forced me to pick one, but answer will vary by mood..
