Hi there, I'm new to the hobby and wanted to ask what is probably a newbie question: is it better to use Dolby Digital Plus or Stereo when watching movies? I know if it's DD+, the receiver will have to down mix it for the speakers but I still don't know if that means better or worse aound. My setup is a Denon x1700h with a left/right 2 speaker setup. Hope to add a subwoofer in the future. Already ran the setup for Audessy. Thanks!

Hello and thanks for having me here. I am interested in various Dreame products especially the Z1 Pro. From what I can tell, the pricing has come down a bit and the firmware is constantly being updated to fix original launch day issues. If you own one at home could you tell me if the updates have made it better? I have an in ground organic shape concrete pool roughly 28000 gal. Thanks!
