From MS2i to GS1000, I'm surprised. The GS1000 is way darker, way more bass, almost too much. I'm not sure if the mid is too much on MS2i or if the mid is recessed on GS1000, but I've some mixed feelings with it. I hope after 876.54 hours, it would sound better
Oh, somebody was auditing a pair of this so I sat down and listened as well and I was blown awaaaaaaaaaaaaaaaaaaaay
