Don't forget this one..you knew I had to do it
Variations between testing on the Headroom graph? That large? Who knows..
The Headroom graph actually makes more sense to me..closer to what I'm hearing.
I personally could care less about these graphs...still interesting to see.
BTW I think those differences on the IF graphs would be audible. There's no real way to know for sure if they're just variations.
Here is the comparison Tyl created.
The differences are VERY slight - I do not believe them to be any more than sample and measurement variation within just one model would cover.
