sounds delays and pausing is not an issue. Moving between sources, powering on and off can on occasion have a very short delay, but definitely not an issue. Btw, some of those delays are based on the OS and lag with streaming services. Not a problem with the sound system. I owned the previous model and upgraded to this beast, and I absolutely love it. eARC is fabulous and I would take this system over any soundbar system on the market.
