In which way does the VC beat the Stellia (except soundstage, which isn’t really hard to beat)?
Well, for me I find the VC more "enjoyable" "fun" etc. I won't go into soundstage as that is obvious. I find tonal balance better with the VC. Lows are much better in my opinion with the VC. Mids have more engagement for me as well. Highs are more in line with what I prefer as well, for me, they have a nice shimmer.
I think that the Stellia might have better imaging and detail retrieval, but only just better, and not worth splitting hairs unless you are going for that sort of thing.
Now if you are going for a more "laid back" analytical sound the Stellia is great...and before I heard the VC the Stellia was what I would say is the best closed back on the market. But I've now heard the VC and it is now my "best" closed back on the market for my use case.
Also to note, I'm basing all of the Stellia points off of limited listening of other peoples Stellias. I think when @Torq gets back and I have to relinquish the VC back to him with tears in my eyes, and heart in my throat. That he will be able to give a much better comparison to the Stellia, as he has them on hand and has more experience with the Stellia than I do.
