I notice you a Tascam US-1641 and I checked it doesn't have Windows 8 drivers yet. That could be your problem. The last driver is dated from 2010.

Thanks John. I will look into that.

I am happy to report the issue is fixed!!!
 
In listening to the mix again, the hiss was there even when I listen to it in X2. Hence, it is not just an Export issue. Once I removed the Stereo Reverb from the tracks, hiss went away. I wonder if the lesson is not to use stereo reverb in a mono track?
 
Thanks for the clues!

You need to use dubley.

You need to use dubley.

Not if it's a rock track.  Everyone knows you don't record rock with dubley, surely?

I would suspect a plugin. Try exporting a file with global bypass enabled and see if the hiss is still there. I recently noticed a subtle hiss in an export and realized it was coming from a tape sim. I just hadn't noticed it until I sat back with headphones and listened closely, away from the computer.
