i had a chance to listen a couple times through my Senn cans. here are my thoughts:
HIGHS: 1 & 2 are very similar. I could barely discern differences between the two. I would have to say, if anything, #1 seems a tad bit brighter. Not by much though.
MIDS: Both samples were silky smooth. A+ in my book for both recordings. No discernable difference.
LOWS: Here is where I found the most difference. I think #2 was more punchy and in your face compared to #1, which I found to be little less "bassy." #1 wasn't lacking a good bass response, it just seemed a bit smoother of a response.
It's tough to tell which one I prefer b/c they are VERY similar. I'm not too familiar with VMS02ib recordings because I haven't critically listened to many sources. I am familiar with the Nbox+ and have an idea which one it is.
By a very slight margin, I'm gonna say I prefer #1.
