donbarzini does raise a good point about feel (That sentence itself is just plain wrong...) but before we take a second to wonder just how on earth donbarzini would go about feeling stuff can I take us back to what been mentioned before about perception... CK is right. The only way forward is to do blind testing. If the difference is that pronounced (And to some it seems that way) they should be able to pick it out above chance levels (P<0.05 etc). This isn't meant to trick anyone - just to remove extraneous variables that could well be influencing people. The sound is easy enough to do (sort of!) with reamped tracks but the feel would present a problem. Unless some of you live near enough eachother to do this in person. Copy a Rig across both machines then conduct blind 'feel' tests - 1.6 vs 1.5.xx
I'm not saying this needs to be done - I personally didn't detect a problem but others seem to and that's a shame. So... in summary who's up for a blind feel test with Diry donbarzini then... ah.
EDIT: I wrote this at lunch but only just posted...things have moved on again but I hope the point is still valid
It must be noted that I was completely nude, only wearing totes galoshes and a head band (lower) when I did this comparison....
