Yes, but 1.6.1 sounds different.
No, seriously. In my case I only spoke for myself. I invested much more time than I wanted on this by creating clips and reamps because I could notice differences on my end. For those to be considered as noticeable enough I guess that depends on each individual but they were there and gone after the system reset. Whether this was useful for you or not and whether you believe it not at this point I guess it is up to you. I just know this to be true IN MY CASE and nothing is going to change that.
Now, I perfectly understand your point. I would have come to same conclusion. Lots of people complained and mostly nobody has taken 5 minutes of their time to demonstrate what they said the were experiencing so maybe they were not even experiencing it. On top of that you are saying that some of the ones that created clips made up their clips with EQs to force them to sound different. Well, that really sucks. Shame for those.
I am thankful you took your time with this anyway.
