Protecting speakers in home theatre application?

I have an Adcom preamp and amp (GFP-565, GFA-535 II) driving a set of B&W Nautilus 804s. I am considering using this with a new TV via a (yet to be purchased) DAC, but I am wondering whether driving the speakers with TV / movie audio with non-music, non-voice special effects audio audio risks damage to the speakers. This includes signal drop-outs / and static-bursts since the HDTV tuner will be over the air broadcast rather than cable.

I looked for prior discussions but did not find them. Any thoughts or pointers to other discussions?

One final comment- I care most about music, not TV and movies, which I just need to hear. I’m not trying to build a theatre. So, I’m hoping to get a rather cheap DAC and maybe a cheap line-level pre-amp with a remote volume control. These components could also be a worry. To be clear, the setup would be to take the digital TV signal via toslink to a DAC; take the line level from the DAC by RCA to the in-line volume control and from there to an AUX in of the Adcom preamp. For music, my CD player goes into another input of the Adcom pre-amp and is free of all this new nonsense...just CD, Adcom pre-amp, amp, and speakers.
