Any opinions? More specifically, has any one done a comparision to see if the speaker emulations are accurate enough to enable realistic mixing/master via just headphones? Being able to do so would be a big help to me.

I just got one and am using it with AKG Quincy Jones headphones. I can definitely hear differences between many of the various configurations, but I don't have enough experience (or equipment) to test the accuracy.

Thanks.
