Safe to use stereo amp for Movies in the long term?

Hi All,

I'm just wondering if anyone here uses a HT Bypass amp connected to AVR amp for movies? Is it safe to do so in the long term? I have a Hegel H360... and it comes with HT bypass. For movies, I normally turn up the volume, close to 70-80db...

Is it safe in the long term or better to avoid it? Thanks...
