I've had open and closed versions of each. Aeolus was the only one I sold only because I found it so similar to the Atticus which I fell in love with first. If I'd bought the Aeolus first I probably would have sold the Atticus--I enjoyed them pretty equally, but the Atticus is a little more fun. The Aelous began to feel like a lesser Verite Open. which I also had then and figured just listen to the Verite if I'm making the Aeolus sound more like it. I did Ori suede on the Atticus and Universe or BE-2 suede on Aeolus, so maybe that's why I find them more similar than some others do. I've been intrigued lately by the Aeolus again, because our tastes are always evolving and I wonder what I might think of it now, especially all my other gear being significantly upgraded since I sold them, so I'll be ordering one again.
I've spent the most time with the VO/VC as far as open/closed models with the same driver and while initially found them very similar, I don't anywhere near as much now and find them definitely different enough to keep both. I think a good case can be made for owning only the 2 Verites because many times when I listen to them, I ask myself why do I even listen to anything else, and have grown to enjoy the VO more than the VC while it was the opposite for the first year I owned both? Even though I have 2 new very impressive headphones with the Atrium and Stax SR-009. They're getting all my head time now but I'll probably ultimately go back to the Verites most, at least until the Atrium closed happens. For my preferences I don't find them lacking in any way.
