Thanks Gasdoc.
Im gonna send mine back to ES for replacement to V2.
After listening for few hours of mostly edm (driven by my RSA Shadow), i felt it does not have the creamy mids provided by the SM3v1. Thus losing much of its body.
Dont mistaken though, the highs are marked improvement and lows are well extended, just without that added punch that i used to love from SM3.
Volume wise, I had to turn up a few steps on my Shadow to match the loudness of my SM3.
Hopefully, the V2 will sound much better and easier to drive.
