Am I killing anything?

[NeilGabriel]

I assume everyone does this. When watching a DVD, usually a music concert, I switch among the various audio tracks for comparison without pausing anything. I never thought much about this but with the new pre/pro I have, I am just wondering if this could cause any problems.

The only damage you could do would be to the speakers if the line inputs are vastly different from analog to digital. I would turn the volume down a little when switching surround modes. You can not hurt the pre/pro.

Ya no harm done. It can actaually be a good way to compare things if you set it up right. Like warlocks said, watch the volume.

I like to play with the different sound modes on my avr/preamp to enjoy what sounds best to me..;)

Yes, music vs HT switching all the time.
