Did I damage my Modi or Magni with this?

I connected my Ps4 to my Modi2u and Magni2u via Optical and accidentally enabled Dolby or Dts bitstream. My headphones made a gruesome buzzing/growling noise for like 10-15 seconds.

Hope this doesn't sound stupid, but could this have in any way damaged my Dac or Amp? Or permanently changed the sound in any way?

I just want to be sure before my new headphones come that it's 100% safe to plug them in and will sound just like before the 'incident'.

Better safe than sorry
