magnesium is lighter by some small amount. I have a Blackwood Atrium feels necessary on those. If your going stock I don’t think you’ll need it but in some of the heavier limited models or a stabalized I’d lean Magnesium.

It spreads out the weight on your head better due to having more surface area. I wear glasses and incidentally I have found I get a better seal too.

Of course. There are two things actually that I suspect are the reason. The first is that the timbre sounds unnatural to me, second issue is on at least the ones I've tried (Audeze Stuff, Ethers, various Hifiman) the higher frequencies don't sound smooth to me. That combination after about 30ish...

Temporarily exiting lurking I went to CanJam NYC to listen to some amps as I'm considering getting a new one. I popped into the ZMF booth to try the Caldera Closed. Full disclosure I don't like planar headphones. They just don't agree with me. I also own far too many ZMFs. I listened to them...

I’m also still waiting. I bought a stabilized VC last year and it took ~3 weeks. That was the fastest I have personally experienced. A little jealous of those that get theirs faster but ZMFs have always been worth the wait.

Thanks for the write up. It confirms what I was hoping for. I got Blackwood 136. Still waiting for mine to ship.

I got my top choice Atrium #136. Been wanting a Blackwood with silver grilles for quite some time.

Very cool solves my problem of having multiple ZMFs and wanting to keep them in one area. Bonus! You have the same combo I have currently VC, Auteur( I did the classic upgrade), and Aeolos.

I had (while lurking) read your review and it's why I was thinking about the Caldera. I think my plan is to try for an Atrium rarity then listen to the Caldera at CanJam NYC and add it to the collection sometime in the future. Related question where did you get that crazy headphone stand? I...

They should be indicating the unique pair so that when you click the drop-down to order you can go right to the number. (that's how it seemed to work for the Macassar Ebony sets)

Long-time lurker, first-time poster. Just want to say I am HYPED!!!!. Torn between one of the Atrium Rarities or the Caldera. Leaning toward the Atrium as I have yet to find a planar I like......
