I have the same experience as you. After burn in it sound more musical to my ear also more meaty smooth detailed snappy fast with deep soundstage. This is my first expensive HP cant talk much about it but my experience is quiet pleasant with VO after listening for a while. But the sound is really niche somehow the tuning is unusual or it is quiet colored. I dont know is this just the tuning or berylium driver character.My first ZMF was the Auteur Classic. Loved it, but knew the VO and the AtriumO were considered "flagships" so I had to hear them. Bought the VO next, and frankly, did not like it at first. Then, after prolonged burn-in and a DAC change, I realized it was system synergy and the extra burn-in that was needed. Fell in love with the VO.
Still wanted to hear the AO, because most descriptions of its sound made me think I would like it, and I knew it was @jinxy245's favorite (and I trust his ears). Bought a used Atrium from head-fier @Superunknown2 , and still have not listened to them a lot (because they are technically a Christmas gift from my wife, and hey it's only 12/5). But, from what I have heard so far, they seem like a great complement to the VO. AO is more reverberant (if that's a word) and spacious. VO is more solid and meaty sounding.
Depending on mood and genre, I can see myself reaching for either one on a given day. May sell the Auteur Classic, but it's too soon to say.
