Randy, I don't listen to Pandora through my axioms. If listening to internet radio it is usually through the network interface of the 3808. I listen to the stations that are available through http://www.radiodenon.com

I am pretty sure that the restorer just boosts the treble and bass a little. I think the difference between the various restorer modes is in the amount of boost that is applied. I usually find the second or third choice to be the best, but it depends on what I am listening to.
