Yes, i have a final tuning prototype of the Atrium closed here with me for the last couple of weeks courtesy of ZMF.Not who you replied to I see you own a VC it sounds like you've heard AC as well. I'm determined to add a pair of ZMF headphones to compliment my LCD-2. I need closed back as I'm wanting a set that has minimal sound leak and good isolation. How would you compare the VC and AC? Is the beryllium driver used in the VC a bit faster than the biocellulose driver in the AC? I'm not huge on doom and stoner (do like it though) and mainly listen to death metal and black metal. I value a punchy, warm signature with fast attack and transients.

The VC is a faster sounding driver, but the mids on the AC are more forward and in my chain, the AC's stage is more expansive. If you want something similar sounding to the LCD-2 you will want the Atrium closed. The sub bass on it is simply killer. OTOH, if you want something that sounds more different than you will want the VC.
I almost always prefer the stock pads on all ZMFs, and the VC and AC are no exception. The VC is much more neutral sounding vs. AC, but if you're not aware pad rolling on ZMFs can have a dramatic impact on how any of their headphones can sound. Still, regardless of the pads being used the AC sub bass is still dominant. If you have a bass heavy upstream chain that can be problematic for the AC. My Lampizator DAC's bass is too much and causes the ACs bass to become overbearing. With the Merason DAC1 the bass is tamed considerably but it still sounds massive. tube rolling will also dictate how much bass you will get out of the AC, assuming you have a tube amp and/or DAC.
The AC and VC next to each other
EDIT: You can also wait until the Caldera closed is released, which is supposed to be sometime this year, but nobody but Zach has heard that yet.
