Denon

I got two "Denon Home 150" speakers as a Christmas present. (Unfortunately not from here, as not yet in the range, there is a discussion about it). Sound: great, very crisp and also powerful bass! The problem: when playing streamed videos/movies via Windows PC with beamer, the sound is not synchronous with Bluetooth. So I connected the speakers to our home network and they are displayed correctly in the control panel. However, nowhere in Windows do I see a way to select the WLAN speakers from the PC so that the sound of the video runs through them. And the HEOS app from Denon unfortunately only works on mobile devices. Is it not possible to control the speakers from a Windows PC via WLAN? Or is there a way to fix the Bluetooth delay? If both are negative, are there any recommended speakers at Galaxus that can either be selected from a Windows PC via WLAN to play back sound from streamed videos, or speakers that can play back sound via Bluetooth without delay when used in this way? (We have a UE Boom 3, with which Bluetooth works without any problems or delays, but it's just not as attractive in the living room and it's also intended for mobile use rather than for stationary use permanently connected to the mains). Many thanks for the help!

I have seen the Denon Heos Amp HS2 and find the possibility of using it with 2 floorstanding speakers as rear speakers with a Denon AV receiver as surround ingenious, as I don't want to lay any cables. My question is now, can I take a 2nd AV receiver from Denon instead of the amp and assign it as a rear? Would be much better again, as the AV receiver has more connections and so I could also connect LP, cassette player etc. there. In other words, 1 location for TV and video, 2nd location for audio only in the same room, but at the same time use this as a surround for movies. Thanks
