Have you compared these to the VC and if so what are your thoughts. Love my Leopardwood VC's. Kept my Auteur Blackwoods for a long time but finally realized they were just collecting dust. Tweaked mine a bit with external tuning devices that improve the PRAT, noise floor and midrange tonality to some degree. Looking at Closed Back Atriums in the future, probably around taxtime. Running them on LOrdGywn's Atrium with Monster's preferred roll in the you tube. Lusting after Western Electrics but 5998's are very nice!
Happy Listening,

When the VO & VC were first being launched, I had both review pairs here for about a week and listened to them both thoroughly on the amps I had at the time, which included the V281 (still my best amp) and the inexpensive but rather nice OTL, the Woo WA3.
I thought the VC was crazy-good. I had owned an Atticus and an Eikon, so I was pretty familiar with Zach's closed-back designs. But the VC was different. The overall sound was distinctly elevated IMO. It had smoothness, beautiful tone, detail, speed, and accuracy all at the same time (unusual to find that). A very musical sounding headphone, but fast, dynamic as hell, great bass & very exciting/great for electric/electronic music. I thought the VC was the best closed back I'd ever heard. The only reason I didn't chase the VC was that closed back dynamic headphones tend to aggravate my migraine & tinnitus. I knew I couldn't handle the explosive sound of the VC. Regardless, it impressed me greatly.
I fell in love with the VO and now own one. It shares many of the sonic attributes of the VC, but because it's open is somewhat more relaxed.
I don't believe I owned an Aeolus at that time, and I certainly didn't own an Atrium, since it didn't exist yet. In the years since I often had opportunities to compare the VO to the Atrium and Aeolus. VO is still my favorite headphone. That headphone just sings to me. But that doesn't change the fact the other two are insanely good headphones.
Then again, any of the four HPs mentioned herein stomp all over most non-ZMF headphones (IMHO).
